The PR20, developed and manufactured by Shenyang Yushi Instruments, is a high-performance, computer-controlled ultrasonic pulse generator and receiver. This device is designed to connect to a computer and an oscilloscope, and it is mainly used in applications such as:
Ultrasonic flaw detection
Thickness measurement
Probe testing
Material analysis
Non-destructive testing (NDT)
The PR20 includes Windows-based control software, which enables users to:
Select trigger sources
Adjust transmit voltage
Set repetition frequency
Control pulse width
Switch between single-crystal and dual-crystal modes
Adjust damping and gain
An open SDK software package is also provided, allowing users to develop custom applications for various mainstream Windows systems.
Damping Control: Multiple levels adjustable
Transmit Modes: Supports Transmit-Receive (TR) mode and Pulse-Echo mode
Repetition Frequency (Internal Trigger): 8 levels adjustable (4Hz–2kHz)
Pulse Width: Adjustable from 1× to 40× (one time ≈ 28 ns)
Transmitting Voltage: 8 levels adjustable, up to 400V max
Maximum Bandwidth: 20 MHz
Receiving Gain Range: 60 dB
Ultrasonic probe testing and calibration
Thickness measurement
Flaw detection in materials
