EUT-104 Portable Digital Four Channel Ultrasonic Detector

The EUT-104 digital four channel ultrasonic detector consists of an EUT-104 four channel PCI board, an industrial computer, and software. The EUT-104 four channel PCI board not only has the characteristics of high repetition rate and high measurement resolution, but also has the advantages of high flaw detection sensitivity, complete functions, stability and reliability, clear interface, and convenient dialogue. It is suitable for universities, research institutions, and factories to quickly form a high-performance and multifunctional multi-channel ultrasonic flaw detector. The EUT-104 digital four channel ultrasonic testing instrument has added many functions to meet the special needs of high-speed automatic flaw detection and thickness measurement of small caliber thin-walled pipes. After being equipped with a high-frequency narrow pulse probe, it can clearly detect the wall thickness echo of Ø 6 × 0.5mm steel pipes, laying a foundation for further analysis.

Portable digital four channel ultrasonic detectorFunction information:

•This instrument can be combined into 1 to 4 channels for multi-channel flaw detection within 4 channels, such as manual flaw detection of single or 2 channels, equipped with combination probes or simple mechanical transmission devices for automatic and semi-automatic flaw detection of 4 channels, etc
This board belongs to a high-performance general-purpose multi-channel ultrasonic PCI board, which can be easily combined with an industrial computer to form a high-performance, fully functional, and widely applicable ultrasonic flaw detector. Therefore, it is particularly suitable for universities and research institutions to carry out flaw detection research
The "N choose 1" function is specially designed for on-site flaw detection with severe white noise and clutter interference in this instrument
If a 1-5MHz broadband narrow pulse probe is used to detect coarse-grained materials or perform other non-destructive tests (such as plate wave tests, etc.), the instrument settings can be adjusted as needed based on the above conditions
The various measurement functions of the gate make it possible to locate defects; The 'bottom wave attenuation' function of the D gate provides a quantitative concept for bottom wave monitoring; The "waveform broadening" of the b/c gate provides conditions for observing and analyzing the details of the echo, and thus determining the nature of the defect
Can be equipped with various probes to complete different detection tasks: such as using a straight probe for longitudinal wave detection, using an oblique probe for transverse wave detection, using a surface wave probe for surface wave detection, using a high-frequency narrow pulse probe for high-resolution detection, etc
The B-scan imaging function not only enables defect imaging, but also reserves sufficient information for further data processing
The stability and reliability of long-term operation are the primary conditions for large forging flaw detectors. This instrument has strict control over temperature drift and long-term operation drift
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
