Testing Platform

Building an ideal testing platform
The ultrasonic pulse generator and receiver can be connected to a computer and an oscilloscope, and with the help of the instrument's built-in control software, it can realize a variety of ultrasonic-related applications, including ultrasonic flaw detection, material thickness measurement, transducer performance analysis, and material property evaluation, etc. Additionally, the system can be used with dedicated ultrasonic transducer testing software to build a complete ultrasonic transducer testing system.
Application of the testing platform in fields such as non-destructive testing
Probe Performance Testing
In the ultrasonic testing process,probe performance directly affects the accuracy and reliability of the test results. The testing platform can analyze the probe's echo signals in both the time-domain and frequency-domain under working conditions,thereby evaluating its performance.

Material Analysis
By using the principle of ultrasonic pulse reflection,the mechanical properties and quality canbe evaluated by measuring the speed of ultrasonic propagation in the material.This method is widely used in the field of materials engineering,particularly in material evaluation and quality control.

Ultrasonic Flaw Detection and Thickness Measurement
This system utilizes the ultrasonic pulse-echo reflection principle and performs flaw detection and thickness measurement by analyzing the echo waveform.Specifically,flaw detection is carried out by evaluating waveform characteristics to determine the presence,size,and location of defects.While thickness measurement calculates the workpiece thickness based on the known sound velocity of the material and the time interval between two echo signals.
