PRM

PRM is a 4-channel pulser/receiver board for the PCI bus. It generates an electrical pulse with a user-defined pulse voltage and pulse width through one of the 4 channels. The pulse is transmitted to an ultrasonic transducer, which converts the electrical excitation pulse to an ultrasonic pulse. The pulse is then propagated into either couplant or the material to be tested. The transducer also receives the echoes reflected from the interface and converts the ultrasonic pulse back into an electrical signal. The on-board receiver processes the signal with the user-defined parameters. The signal from the Signal Out connector can be displayed by an oscilloscope or digitized by an analog to digital converter board.

Other adjustable parameters of the PRM board include pulse voltage, pulse width, damping, internal relay for pulse/echo or through transmission switching, receiver gain, DC offset, low pass filter, high pass filter, rectifications, trigger sources, digital inputs and outputs, and internal trigger rates. The user selects the pulsing channel and the receiving channel, which are not necessarily the same. Control software for Windows 95/98/2000/NT is included.

Optional add-ons include digital inputs and outputs, a trigger-sync output connector, a logarithmic amplifier, up to 4 encoder counters, a higher pulse voltage, narrow and wide pulse widths, distance amplitude correction (DAC), and Windows software development kits.

For the option of analog to digital conversion, please refer to our product UTM--the 100 MHz analog to digital converter board for PCI bus with 4 pulser/receiver channels. Refer to PCIPR300 pulser/receiver board and DT16B 16-channel pulser/receiver switching board for more channel solutions.
