Applications of PR32 in NDT and Material Analysis
As a high-performance desktop test platform, the PR32 ultrasonic pulser receiver is designed to solve complex inspection challenges. Its flexible signal generation, ultra-low noise receiver, and open SDK make it ideal for a wide range of non-destructive testing and material characterization applications.
Probe Performance Test
Probes are critical in ultrasonic testing; their performance directly affects the accuracy of results. The PR32 measures and analyzes both the time domain response and frequency domain response of echo signals from probes in working state, enabling systematic evaluation of transducer performance.
Time domain response · Frequency domain response · Transducer analysis
Ultrasonic Flaw Detection & Thickness Measurement
Based on the ultrasonic pulse reflection principle, waveforms are measured and analyzed. Flaw detection determines the presence, size, and location of internal defects, while thickness measurement accurately calculates workpiece thickness using material sound velocity and echo time intervals.
