The basic principle of PT series ultrasonic thickness meter

Ultrasonic thickness meter is based on the principle of the ultrasonic pulse reflection for thickness measurement, when the launch of the ultrasonic pulse probe through the material object to be tested interface, the pulse is reflected back to the probe, through the accurate measurement of ultrasonic wave propagation in the material time to determine the thickness of the material being tested. Those that make the ultrasonic wave at a constant speed in its internal communication of various materials on the principle of the measurement. According to the principle of the design of the thickness gauge can accurately measure about all kinds of plates and all kinds of machining parts, can be all kinds of pipeline and pressure vessel in the production equipment to monitor, monitor them in the process of using the degree of corrosion after thinning. Can be widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields.
PT series ultrasonic thickness meter using techniques and factors affecting the accuracy of measurement
1, the general measurement methods:
(1) in a place with a probe for two thickness, the two split face to each other in measuring probe 90 °, measured the thickness of the workpiece is a smaller value.
(2) 30 mm multipoint measurement method: when the measured value is not stable, with a measuring point as the center, in many times within the circle of about 30 mm in diameter measurement, taking the minimum value to be measured the thickness of work piece. 2, accurate measurement method: increase the number of measurement around the specified measurement point, expressed in isopach thickness changes.
3, continuous measurement method: along the designated route continuous measurement with single point measuring method, interval is not more than 5 mm.
4, grid method: in the designated area in the grid, the thickness at the record. This method in the high voltage equipment, stainless steel liner is widely used in corrosion monitoring.
5 and the influencing factors of ultrasonic thickness meter value indicated:
Large (1) the surface roughness of workpiece and the probe and the interface coupling effect is poor, low echo, and even can't receive the echo signal. For surface rust, and coupling effect is poor equipment and pipelines in service through sand, grinding, cutting method for surface treatment, such as lower roughness, oxide layer and paint can be removed at the same time, with metallic luster, make the probe and were seized by the coupling agent can achieve very good coupling effect.
(2) the workpiece curvature radius is too small, especially the small tube thickness, for common probe surface is flat, contact with the surface of point contact and line contact, low sound intensity transmissivity (coupling). Can choose special probe (6 mm), small diameter can more accurate measurements of pipeline surface materials, etc.
(3) the detection of surface and bottom surface is not parallel, sound waves encountered bottom scattering, the probe can't accept what wave signal.
(4) the austenitic steel castings, due to uneven or coarse grains, in which ultrasonic through severe scattering attenuation, scattering of ultrasonic wave propagation along the path of complex, has the potential to echo annihilation, cause is not shown. Can choose the coarse grain special probe of low frequency (2.5 MHz).
(5) probe interface has some wear and tear. Commonly used thickness probe surface for the acrylic resin, long-term use can make the surface roughness increases, resulting in a decline in sensitivity, resulting in the display is not correct. Can choose 500 # sandpaper, make it smooth and ensure parallelism. If it is still unstable, consider replacement probe.
Analyte (6) there is a lot of corrosion pits on the back. Analyte due to the other side has a rusty spot, corrosion pits, cause the acoustic attenuation, lead to reading no rules change, in extreme cases even without reading.
(7) (such as pipe) object to be tested with sediment, sediment and artifacts when acoustic impedance difference is not big, thickness gauge display value of wall thickness and thickness of sediment.
(8) when the intrinsic defects in the material (such as inclusions, sandwich, etc.), the display value about 70% of the nominal thickness, such as defect detection by ultrasonic flaw detector further at this time.
(9) the influence of the temperature. Average velocity of solid materials decreases with the temperature, and there are test data show that hot materials increase 100 ° C, a 1% drop in the speed of sound. For high temperature equipment in service often encounter this kind of situation. Should choose special high temperature probe (300-600 ° C), do not use the ordinary probe.
(10) cascading material, composite (heterogeneous). To measure without the coupling of the laminated material is not possible, due to the ultrasonic cannot penetrate without coupling space, and are not uniform in the composite (heterogeneous) transmission. For equipment made of multi-layer material bandage (like urea HP equipment), should pay special attention to when thickness, thickness gauge says only the value of the material thickness is in contact with the probe.
The influence of coupling agent (12). Coupling agent was used to eliminate the probe and the air between the object to be tested, make the ultrasonic wave detection can effectively through the workpiece to achieve. If choose types or improper use, will cause the error or coupling symbol flashing, you can't measure. Because, according to the types of usage for choosing appropriate when materials used in the smooth surface, the coupling agent can use low viscosity; When used at the top of the vertical surface and rough surface, surface, high viscosity of the coupling agents should be used. High temperature artifacts should choose high temperature coupling agent. Secondly, coupling agent should be used in moderation, evenly daub, general coupling agent should be coated on the surface of the material being tested, but when the temperature is higher, the coupling agent should be coated on the probe.
Select error (13) sound. Measurement of workpiece, the speed of sound or according to the standard block according to the material types preset counter measure the speed of sound. After correction instrument with a material (commonly used for block, steel) and to measure when another material, will produce the wrong results. Requirements must correctly identify materials before measurement, appropriate velocity of sound.
(14) the effects of stress. Equipment in service, most of the pipeline stress exists, the stress condition of solid materials has certain influence to the velocity of sound, when stress direction is consistent with the direction of propagation, if stress is compressive stress, the stress increase the elasticity of artifacts, velocity of sound speed up; On the other hand, if stress is tensile stress, slowed the speed of sound. When stress with the direction of wave propagation is differ to, fluctuations in the process of particle vibration trajectory, the influence of the stress wave propagation direction deviation. According to the data show that average stress increases, the speed of sound increases slowly.
(15) metal surface oxide or the influence of paint coating. The density of the metal surface oxide or paint coating, though close integration with the base material, no obvious interface, but the speed of sound propagation velocity in two kinds of material is different, resulting in the error, and with the cover thickness is different, the error size is also different.

The us local time on February 24, 2011, Intel officially released have months of Intel lab products, code-named ThunderBolt ultra-high-speed interface technology
"Light Peak" technology [1], and named it "Thunderbolt" (lightning). Thunderbolt technology designed by Intel in 2009, and named as "Light Peak" (codename is Thunderbolt), Thunderbolt research purpose is to replace and unified the present number of computer performance of jagged extension interface, such as SCSI, SATA, USB and FireWire and PCI Express. Thunderbolt is apple cooperation with Intel (Intel), developed by Intel, through technical cooperation with apple to the market. The technology is mainly used to connect PCS and other devices, combines the two mature technologies before PCI Express data transmission technology and DisplayPort display technology, two channel can transfer these two protocol data at the same time, each channel to provide two-way 10 GBPS bandwidth. In order to reduce costs, the Thunderbolt is copper connection way rather than earlier demonstration of optical fiber links, the theoretical maximum transmission rate can be up to 50 GBPS, now only setting in 10 GBPS, larger development space.
Working principle and performance
Thunderbolt connection technology integration is a blend of PCI Express data transmission technology and DisplayPort display technology, Thunderbolt works by a special control chip to drive, Intel through PCI Express x4, DisplayPort bus are connected to the system chip. PCI Express is used for data transmission, DisplayPort is used to display signal transmission, also can through the direct connection Intel integrated graphics processor core DisplayPort display output. Thunderbolt control chip, which is indispensable in the system. However, Intel said it hardware needs no Intel processors and chipsets. It's more like a miniature router, can quickly switch between two two-way channel data. Thunderbolt adopted special interface. The interface of the physical appearance is the same as the original Mini DsiplayPort interface, suitable for all kinds of light, small equipment, compatible with DisplayPort interface display device, the Mini DP interface display and Mini DP to HDMI/DVI/VGA interface connector can be normal use on a Thunderbolt interface, can transmit 1080 p and high-definition video and most 8-channel audio. Does the Thunderbolt backwards or forwards compatibility depends on the use of cables. Backwards compatible with PCI Express 2.0 I/O control system, but Intel for USB 3.0 no comment. And forwards compatibility, nature is as new as possible, you can find the new port has been on the Macbook Pro ready for optical fiber transmission, it is more cost-effective. Each interface transmission speed according to the connection equipment technical support to a Daisy - chain Thunderbolt Daisy chain form 7 devices connected together, (which is what apple MacBook Pro series 6 sets of peripherals, including up to two full hd DisplayPort display output), but requires DisplayPort 1.1 the equipment must be located at the end of the link. In order to reduce costs, the Thunderbolt is copper connection way rather than earlier demonstration of optical fiber links, the copper wire length is 3 meters. Later this year, will also introduce fiber optic cable products. Copper wire, however, still retain an advantage in the future, that is providing the 10 w power supply cable, and optical fiber Thunderbolt won't provide power supply function.
Currently use
In apple's new MacBook Pro with a Thunderbolt ports at the same time, there are many brand announced Thunderbolt related products, including Aja, Apogee, Avid and Blackmagic. Third party support, Intel said western digital and LaCie will provide compatible Thunderbolt interface of mobile hard disk. Among them, the LaCie has shows a use Thunderbolt device, double SSD do Raid storage devices, and, of course, because of the limitation of storage Thunderbolt's fighting capacity is really hard to show up in the home. 
This speed for home is too far, luxury three meters of line length also greatly limits the scope of its use, I can think of the possible applications are:
* multi-monitor support, because can single port to six devices, in theory, you can organize 7 screen work platform. 
* high-speed disk array by SSD erect Raid, extremely exaggerated disk performance can be obtained with Thunderbolt, for image processing, image rendering and other professional work is good. 
Of course, with the expansion of the technology, a large number of peripherals appear later, Thunderbolt high transmission speed and the ability of single interface equipment will gradually showed its advantages. Coming of fiber optic connections to a single Mac machine for computing the core, with a large number of related peripherals, decorated a seems to be the centralized processing environment, over the next year, you can start to update the current home network.
foresight
The apple PC will be in the coming year, exclusive patent rights, the technology more PC makers began to open next year to sell the pillar. It said apple on using Thunderbolt technology compared to other manufacturers have the advantage of a few months to a year. Currently has confirmed that will launch a Thunderbolt peripherals products including Promise Pegasus (RAID), LaCie (Little Big Disk), western digital, etc. Because the Thunderbolt transmission speed is now are using data interface of 10 to 20 times, may be some of the existing interface, and the use of our habits cause certain changes. 
The following for the Thunderbolt may bring the change:
- data transmission speeds of up to 10 GBPS, 20 times for USB 2.0. From a practical point of view, this means you can transport a complete within 30 seconds blu-ray discs, or in a few seconds of time video transmission over 2 gb. 
- it has two independent transmission channels, ascending and descending support "Daisy chain" (Daisy chaining) more equipment, so the video can be exchanged between multiple devices at the same time. - it will be compatible with a large number of devices: a Thunderbolt interface supports both relatively new DisplayPort display interface, also support the hard disk devices such as the use of PCI Express interface. Support means that can be easily to develop other PCI interface adapter, Thunderbolt and Ethernet switches, for example, or Thunderbolt and wire converters, etc. 
Thunderbolt will appeal to the media production companies and professional support, including professional audio and video editing software maker Avid, many enterprises have become the first to support the technology of the company. It's also worth noting that, Thunderbolt is not able to bring changes to the video itself. Bottleneck affecting the effects of video and there are many, including graphics processor and operating system restrictions. Once you want to upload video to the Internet, bandwidth speed will also be a big problem. But recall of MP3 gradually rises in the 1990 s: a portable MP3 player to store music time is very short, very poor sound quality, making and player software, and it also can use slow dial-up network to upload and download music. After a few years, apple and other companies to improve gradually, and bandwidth are rising. Today, almost all the people who owns the computer can use a computer to store, transfer and play music. Computer music has become the mainstream. So after 5 years, it is easy to imagine that when users to create, copy, and exchange of a large number of video file, also will receive audio files with the same convenience. Thunderbolt is not a sufficient condition, but it eliminates a major bottleneck. At least for now, Thunderbolt interface is not a must, because there's almost no equipment can use this interface, but in the long run, Thunderbolt must allow the user to reduce many trouble in the future, because the Thunderbolt almost can replace all the extended interface.
Magma ExpressBox 3 t company is the world's first support the expansion of the lightning technology products. ExpressBox 3 t will officially start selling in the fourth quarter of 2011.

As the Misson company PCI/PCIe docking stations of the sole general agent in China, we have already sold more than 417 docking stations (statistics in the year to March 22, 2011), thank you for your support. Now everyone more concern and consulting the answers here, hope to help you choose and buy.
What's the PCI Q01: laptop docking stations for? The server can use PCI docking station?
A01: PCI bus has a fast transfer rate, plug and play, interrupt sharing, and many other advantages, so there are many devices is PCI interface, but PCI devices often can only be used on the desktop, so you don't have the portability. In the field of mobile operations is very inconvenient. PCI laptop docking station can solve this difficult problem. User insert PCI devices within the docking station, and then through a special cable to connect to the laptop adapter card, can through the notebook to use PCI devices.
PCI docking station can be used on the server, at this time to choose PCIe or PCI interface adapter card. Especially now many have no new server PCI interface, when users need to use PCI CARDS on the server, the docking station can satisfy the use requirement.
What is the distinguishing feature of PCI Q02: laptop docking station?
PCI how A02: laptop docking station has the following features:
(1) no attenuation speed, the adoption of hardware protocol conversion, after PCI devices barge received notebook, attenuation and PCI bus data without any delay;
(2) different models of docking stations can insert half length and total length, half tall card and all the high card, 32-bit PCI card, 64 PCI card, and PCI - X CARDS;
(3) different models of docking stations 1, 2 blocks of pluggable, four, six, seven or even 13 pieces of PCI card;
(4) small size, easy to carry. Especially the single slot PCI docking stations, the volume of a full-sized is 341 x138x43mm, only half a long only 341 x138x20. 37 mm;
(5) all aluminum shell, good heat dissipation, light weight. Single slot dock weighs less than 1 kg, the expansion of the double groove dock weighs 2.4 kg;
(6) docking station built-in DC - DC circuit, which can realize PCI card DC power supply, especially suitable for field operation;
(7) for the original production, stable and reliable quality, coupled with PengXiang technology for up to 3 years of quality assurance, the user no worries;
(8) in addition, some relatively expensive PCI devices, inserted inside the computer for a long time in current state, the impact on the life of the product must have, and use only after the docking stations need electricity work in data acquisition, once the data stored in the disk can be closed after the docking station, the data analysis or editor at PCI devices need not, greatly extend the service life of the PCI devices.
PCI - E Q03: laptop docking stations and PCI docking stations have what differentiation?
PCI - E A03: laptop docking stations from laptop extend out PCI - E interface, and PCI expansion dock was PCI interface. PCI - E is short for PCI Express, is the new generation of bus interface. PCI - E interface varies according to the bus bits wide, including X1, X4, by 8 and X16 specifications. PCI Express X1 specifications to support every two-way data transmission, data transmission bandwidth 250 MB/s, PCI Express X16 support two-way data transmission, each to the data transmission bandwidth up to 4 gb/s, the bidirectional data transmission bandwidth of 8 gb/s. Notebook PCI - E docking station can be extended from the laptop out multiple PCI - E slot.
Q04: how the dock price is so high, IBM has a pluggable PCI card's docking stations to hundreds of yuan, why there are so much difference?
A04: yes, IBM has been producing a docking station, but can only be used under the T30 models of laptops, and only half long card. The docking station official offer is 8650 yuan, already stop production for many years, at present the basic it is teardown on market or second-hand.
MISSON companies in the United States of the docking station is suitable for most types of laptop, multiple length can be inserted card, 32-bit or 64 - bit PCI card, PCI - X card, PCI - E card.
Is not a type of product, both in price and similar (not second-hand IBM docking stations and the MAGMA compared new with 3 years warranty, products of the company)
Q05: when buying a laptop docking station PCI, how should I choose a laptop adapter card?
A05: there are three kinds of docking stations PCI adapter card, can choose any one. What is you need to check your notebook interface, if is PCMICA interface, can choose Cardbus adapter card. If it is an ExpressCard 34 or an ExpressCard / 54 of the interface, the choice of the EC34 or EC54 adapter card. Is highly recommended to choose EC34 adapter card, because EC34 adapter card can be inserted into an ExpressCard / 54 slot, but EC54 adapter card can not insert/an ExpressCard 34 slot.
In general, the expansion of the older models of laptop slot PCMICA interface, a new model is generally ExpressCard34 slot.
Notebook PCI - E docking station adapter card only EC34 this one.
PCI Q06: laptop docking station how to implement a dc power supply?
A06: place the battery in the docking station or from a mains socket received the docking station. We also have 8 ah ~ 18 ah capacity of built-in lithium battery standard accessories.
Q07: notebook PCI/PCI - E docking station how to use?
A07: notebook PCI/PCI - E docking stations use is very simple, only three steps, please see the notebook PCI docking station installation method of use: http://www.ndttech.net/support/pci_support/pci_setup.html
Compatibility of PCI Q08: laptop docking station?
PCI A08: laptop docking station has good compatibility, suitable for most of the brands most of the models laptop, and most of the data acquisition card, movement control CARDS, non-linear editing card, effect of video audio card, network communication, optical fiber adapter card and so on PCI devices. PCI so far we have sold more than 300 laptop docking station, only one customer to the actual test, it found that are not compatible, then confirm with the customer the PCI card is a research and development of their own, and they also reveal the PCI card on the part of the desktop can't normal use, is to choose the mainboard, so that the docking station has good compatibility.
Q09: notebook PCI/PCI - E docking stations of quality assurance and after-sales service policy?
PCI A09: laptop/PCI - E docking stations of MTBF (MTBF) for 25000 hours, all products have passed the FCC class A certification and CE quality certification.

Acceleration sensor is one of the main products of the Fuji ceramics co., Fuji in Japan ceramics occupy more than 60% market share of the acceleration sensor, including nearly half of the OEM market.
1, what is the acceleration sensor
Acceleration sensor is a kind of electronic devices that can measure acceleration. Acceleration is when an object in the process of acceleration forces acting on the object, is like gravity, that is the force of gravity. Can is a constant acceleration forces, such as g, also can be variable.
It usually takes 2, acceleration sensor in where
By measuring the acceleration caused by gravity, you can calculate the equipment relative to the horizontal plane Angle. By analyzing the dynamic acceleration, you can analyze the equipment moving way. But in the beginning, you will find that the optical measuring Angle and acceleration seems not very useful. But now, engineers have come up with so many ways to get more useful information.
Acceleration sensor can help you in the environment of robot know it now. Is climbing a mountain? Or is going downhill, fell down without? Or for flying robot type, to control the attitude is also very important. More to make sure that your robot to crowded places with a bomb themselves. A good programmer can use acceleration sensor to answer all the questions. Acceleration sensor and can be used to analyze the vibration of the engine.
Acceleration sensor can measure the traction of acceleration.
At present the latest IBM Thinkpad laptop has a built-in accelerometer, can the dynamic monitoring of the notebook in the use of vibration, and on the basis of the vibration data system will be smart choose to shut down the hard disk or let it continue to run, so can the greatest degree of protection due to vibration, for example, the working environment of turbulence or accidentally fell computer hard disk damage, maximum to protect the data inside. Another useful is currently used in digital cameras and video cameras, and acceleration sensors, used to detect when the vibration of the hand, and on the basis of the vibration automatically adjust the camera's focus.
In summary, the acceleration sensor can be used in the control, handle vibration and shaking, instrument and meter, auto brake start test, seismic detection and alarm system, toys, structure, environment monitoring, engineering vibration, geological exploration, railways, Bridges, vibration test and analysis of the dam; Mouse, high-rise building structure dynamic characteristics and security surveillance on vibration. Acceleration sensor can also be applicable to earthquake monitoring, low frequency applications, test equipment, mechanical control, etc.
3, the acceleration sensor is how to work
The principle of linear accelerometer is the principle of inertia, also is the force balance, A (acceleration) = F (inertial force)/M (quality) we only need to measure F is ok. How to measure F? Electric magnetic force to balance the force. You can get F corresponds to the current relationship. Only need to calibrate the scale factor by experiment. Of course is in the middle of the signal transmission, amplification, filtering circuit.
Most of the acceleration sensor is working according to the principle of piezoelectric effect.
Piezoelectric effect is the so-called "for there is no center of symmetry ionic crystals in crystal on the external force except in the crystal deformation will also change the crystal polarization state of the electric field are established within the crystals, this happened due to mechanical force make the medium polarization phenomenon called positive piezoelectric effect".
General acceleration sensor is in using its internal crystal deformation due to the acceleration of this feature. As a result of this deformation can produce voltage, as long as the applied voltage and calculated the relationship between the acceleration and acceleration can be converted into voltage output. Of course, there are many other ways to make the acceleration sensor, such as pressure resistance technology, capacitance effect, the hot gas bubble effect, the effect of light, but its basic principle is due to the acceleration produces a certain medium deformation, by measuring the deformation and relevant circuit is converted into voltage output. Each technology has its own opportunities and problems.
Piezoresistive acceleration sensor is fastest growing due to widely application in automobile industry, the acceleration sensor is mainly used for automobile such as airbags, antilock brakes, traction control system security performance. Owing to security is more and more become the selling point of automobile manufacturers, the additional system also more and more. Piezoresistive acceleration sensor is the size of the market in 2000 about $420 million, according to the investigation, its market value is expected at 4.1% of the annual average growth rate, to $560 million in 2007. This among them, the European market fastest, because Europe is home to many airbags and automobile production enterprises.
Piezoelectric technology is mainly used to prevent the machine from the fault in the industry, the use of this sensor can detect potential of machine fault in order to achieve self-protection, and avoid produce accident harm to workers, this kind of sensor has users, especially the quality of industry's pursuit of repeatability, stability, and the user from nature. But in many new application fields, many users, there is no use of this kind of sensor consciousness, sellers venturing into this is yet to be developed by the market will be a lot of trouble, because the end user by using this sensor and the problems and solutions are known. If these problems can be solved, will promote the development of piezoelectric sensor to get faster. Piezoelectric sensor market value of $300 million in 2002, its annual growth rate is expected to reach 4.9%, to $420 million by 2007.
Capacitance sensor is expected to have a strong growth, growth will be faster after 2004, estimates from 1997 to 2007, compound annual growth rate of 5.9%, the highest can amount to 33.2%, its market value in 2000 was $075 million, will reach $110 million by 2007. From Europe and North America's auto industry and industrial users are the main buyers of these products. On the market of North America in 2000 accounted for 40.4%, European 48.9%. Auto industry using capacitive sensor is mainly used for security system, tire wear monitoring, inertia brake lights, headlights and leveling, seat belt scale, automatic door locks and airbag. For designers, capacitive sensor is very attractive, because it would not contact, the object under test so you don't have to squeeze into the narrow space.
4, acceleration sensor when the choose and buy, need to consider
The digital output of analog output vs:
This is the first to consider. This depends on your system and interface between acceleration sensor. General analog output voltage and the acceleration is proportional to, such as 2.5 V corresponding to the acceleration of 0 g 2.6 V corresponds to 0.5 g acceleration. Digital output generally use pulse width modulation (PWM) signal.
If you use the micro-controller only digital input, such as the BASIC Stamp, you can choose the digital output acceleration sensor, but the problem is that you have to take up additional a clock unit for processing PWM signal, at the same time, the processor is also a big burden.
If you're using microcontrollers have analog input port, such as the PIC/AVR/OOPIC, you can use to simulate the interface is very simple acceleration sensor, all that is needed is in the process to join a similar "acceleration = read_adc ()" command, and deal with the speed of the order as long as a few microseconds.
, the number of measuring shaft:
For most of the project, two axis acceleration sensor can already satisfy most application. For some special applications, such as UAV, the ROV control, triaxial acceleration sensor may be suitable for a bit.
, the maximum measured value:
If you as long as the robot relative to the inclination of the ground, that a plus or minus 1.5 g acceleration sensor is enough. But if you need to measure the dynamic performance of the robot, plus or minus 2 g should be enough. If you have such as robots will suddenly start or stop, then you need a plus or minus 5 g sensor.
The sensitivity,
In general, the more sensitive, the better. The more sensitive sensors are more sensitive to changes to a range of acceleration, the change of the output voltage is, the greater the so it is relatively easy to measure, in order to gain more accurate measurements.
• bandwidth
In this case, the bandwidth is actually is the refresh rate. That is to say, every second sensor will produce how much time reading. For as long as the application of measuring Angle, average of 50 HZ bandwidth should be sufficient, but for the need for dynamic performance, such as vibration, you will need a sensor with hundreds of HZ bandwidth.
• resistance/caching mechanism
For slightly controller, must carry on the A/D conversion, the connection of the sensor resistance value must be less than 10 k Ω. The acceleration sensor resistance to 32 k Ω, for example, in the PIC and AVR on the control panel can not work normally, so advice before buying sensor, carefully read the controller manual, to ensure that the sensor can work normally.
