EUT-101C is able to measure the velocity of sound automatically, detect rapidly, playback waveform, get defect imaging and store data.
EUT-101C has outstanding advantages, such as high sensitivity, high resolution, and broadband. With the support of fast response in high frequency receiver and amplifier and high-speed sampling technology, the underside of the instrument resolution was greatly improved, therefore it’s much easier to detect and identify small cracks.
KEY FEATURES
· With quite high of transmitting pulse amplitude (Up≥600V), quite steep of front edge rise time (tr≤15ns) , quite low of effective output impedance (that is the load capacity is quite strong), EUT-101C has very high sensitivity and very high resolution.
· With outstanding advantages of high input impedance, bandwidth, high signal-to-noise, and high fidelity of echo. It can be used not only for high-sensitivity flaw detection of large forgings, but also for high-resolution inspection of aircraft and auto parts.
· The 15m testing range enables to observe the shaft end echo of the 600,000-kilowatt rotor.
· Various measurement methods of gates enables more accurate location. The waveform widening of gate b/c gives details of echo analysis.
· It is designed with replay function to record and store the dynamic waveform for long time, which makes it much more convenient for storage, analysis and remote diagnosis.
· B scan imaging can be showed on the screen with A/B scan.
· Has strict control for temperature drift and long-time running drift.
· The high performance transmitting system can effectively excite the high frequency narrow pulse probe of 10-20MHz and obtain the echo pulse with sufficiently high amplitude and relatively small ringing period.
· The 0.5-20MHz wideband receiving system amplifies the echo pulse from the high-frequency narrow pulse sensor and sends it to the digital circuit for further processing. And the 3-20MHz requency range helps to higher the near field resolution for2.5mm*Φ0.4mm flat-bottom hole.
· The instrument adopts man-machine dialogue interface, which is easy to understand and operate.
· Enables to image, play back, analyze for stored data, and to create and print the report.
· Testing paramters and testing data can be saved and called out when needed.
· The scanning data can be transmitted via network port or USB port, and the computer imaging analysis software can be used to realize the computer management of the testing results.
· With the rapid development of computer technology, this machine has faster signal processing speed, wider frequency range, better probe compatibility, larger storage capacity, higher intelligence, more reasonable interface design.
· Built-in lithium battery for long-time working per charge.
· Languages available in English and Chinese.
