Main Functions of Pulse Generator and Receiver-NDT & Material Analysis Solutions
Ideal Probes Testing Platform
Using PR series Ultrasonic pulse generator and receiver can measure the actual probe frequency by analyzing the time-frequency domains. Such inspection can optimize the sensitivity and accuracy of thickness measurement or flaw detection.
Material Characteristic Evaluation
The pulser receiver can be matched to the oscilliscope, which can display the whole waveform. Inspectors can detect the internal defects and identify the sound velocity.
Ultrasonic Testing Device
PR series pulse generator and receiver can optimize the results of ultrasonic thickness testing and ultrasonic flaw detection.
