Configuration of EUT-103 Ceramic Insulator Ultrasonic Imaging Testing Instrument

EUT-103 is a new product developed for ultrasonic testing imaging of ceramic insulators and bushings. The software interface, shortcut key function settings, A/B scanning screen display, and recording and storage of inspection results of the instrument all meet the requirements of relevant testing standards and specifications for ceramic insulators and porcelain sleeves. It can achieve automatic measurement of material sound velocity, rapid inspection, waveform playback, defect imaging, and data storage on site. With the support of fast response of high-frequency receiving amplifiers and 400MHz high-speed sampling technology, the bottom resolution of the instrument has been greatly improved, allowing for the detection and resolution of small cracks on the outer wall of ceramic pillars. It can also be used for ultrasonic testing of forgings, welds, and general workpieces, making it particularly suitable for achieving the goal of multi-purpose use in power systems. EUT-103 also has outstanding advantages of high sensitivity, wide bandwidth, and high resolution. With the support of fast response of high-frequency receiving amplifier and 400MHz high-speed sampling technology, the bottom resolution of the instrument has been greatly improvedThe improvement provides convenience for detecting and distinguishing small cracks on the outer wall of ceramic pillars during on-site inspection.

Configuration of Ultrasonic Imaging Testing Instrument for Ceramic InsulatorsFunction information:

·It has a relatively high emission pulse amplitude (Up ≥ 500V) and a sufficiently steep leading edge rise time (tr ≤ 15ns), and also has a very low effective output impedance (i.e. its load capacity is quite strong), which can effectively excite high-low frequency probes of various chip sizes to achieve high sensitivity and high resolution flaw detection
·It has outstanding advantages such as high input impedance, wide bandwidth (with both hardware narrowband and broadband), high signal-to-noise ratio, and high fidelity transmission of echoes. It can be used for high-sensitivity testing of large forgings, as well as high-resolution testing of aircraft and automotive components
·The instrument has pre stored 28 amplitude curves of crawling wave probes for various specifications of porcelain pillar insulators, as well as instrument parameters for longitudinal and transverse wave probes, for on-site reference
·The specially equipped playback function can record/store the dynamic waveform of the flaw detection for a long time, providing convenience for archiving the flaw detection process, expert analysis, and remote diagnosis
·The B-scan imaging and A/B-scan display functions on the same screen, which can achieve defect imaging and reserve sufficient information for further data processing
·The stability and reliability of long-term work are the primary conditions for large forging flaw detectors. This instrument has strict control over temperature drift and long-term work drift
·The high-performance transmission system can effectively excite the 10-20MHz high-frequency narrow pulse probe and obtain echo pulses with sufficiently high amplitude and relatively few ringing periods
·The 0.5-20MHz broadband receiving system can amplify and transmit the high-frequency narrow pulse probe's echo pulse with high fidelity to the digital circuit for further processing; In addition, the 3-20Hz low-frequency suppression broadband range of this instrument is beneficial for improving near-field resolution, providing instrument support for clear resolution of 2.5mm diameter flat bottomed holes on the near surface
·The use of high-frequency narrow pulse probes provides instrument conditions for achieving high near-field/far-field resolution, making it particularly suitable for situations where shallow or small defects need to be discovered
·Equipped with crawlers or mechanical scanning devices for automatic or semi-automatic inspection
·The instrument adopts a human-machine dialogue interface, which is clear and easy to understand, easy to operate, and has hotkey help prompts
·Random matching computer software can perform functions such as imaging of stored records, playback, analysis, or printing of generated reports;
·Ultrasonic testing parameters, graphics, and files can be stored in the instrument's 4G memory and accessed at any time
·Scanning data can be transmitted to desktop computers or similar instruments through network or USB ports, and then computer imaging analysis software can be used to achieve computerized management of the results of the flaw detection process
·The rapid development of computer technology has further improved the signal processing speed of instruments. Compared with the original instruments, the detection frequency range is wider, the probe compatibility is better, the storage capacity is larger, the degree of intelligence is higher, and the interface design is more reasonable
