Ultrasonic Tone Burst Pulser/Receiver and A/D Board for PCI Bus
The PCIUT3100T ultrasonic testing board is a combination of tone burst pulser/receiver and high-speed analog to digital converter on a single PCI board. The board generates a series pulse chain which is transmitted to an ultrasonic transducer. The transducer converts the electrical excitation pulse chain to an ultrasonic pulse which then propagates into the test material or couplant. The transducer also receives the echoes that are reflected back from the interface and converts the ultrasonic pulse back into an electrical signal which is then processed by the on-board receiver and analog to digital converter. This process is entirely adjustable by the end user - configurable properties include: pulse voltage, pulse frequency, number of pulse cycles, damping, pulse/echo or through transmission mode, receiver gain, DC offset, low-pass filter, high-pass filter, rectification, sampling rate, trigger source - internal or external, and trigger delay.
Optional add-ons include digital inputs and outputs, an external clock input, a sync output, memory updates, an onboard hardware key module, a logarithmic amplifier, distance amplitude correction (DAC), up to two additional 14-bit analog to digital converters, up to 4 quadrature encoder counters, and software development kits.
Multiple PCIUT3100T boards can also be installed in one computer to develop a multi-channel ultrasonic system capable of firing multiple transducers and acquiring data at the same time.
Applications include distance measurement in air and flaw detection in concrete, wood, honeycomb, foam, bonding, composite material and high temperature material. The tone burst pulser also helps the regular ultrasonic test by providing more energy to the ultrasonic transducers.
