The ultrasonic preamplifier models for use with ultrasonic flaw detection, thickness gaging, and acoustic emission instrumentation provide very low noise amplification of ultrasonic signals.
Olympus wideband series of Panametrics AC coupled, broadband preamplifiers provides very low noise amplification of ultrasonic signals ranging from 500 Hz to greater than 40 MHz. Specifically designed for use with ultrasonic flaw detection, thickness gaging, and acoustic emission instrumentation, our preamplifiers are a cost-effective solution in general applications requiring high gain/low-noise amplification of low amplitude ultrasonic signals.
Our preamplifiers are ruggedly housed, completely self-contained, simple to operate, battery or AC powered units. They offer performance features such as very low noise (5 µV peak-to-peak noise referred to the input in Model 5660B), input protection for high voltage transients such as transducer excitation pulses, and the ability to drive long coaxial cables (greater than 500 feet or 152 meters with Models 5660B and 5660C). Both fixed gain and switchable gain versions are available, and custom units with special gain or bandwidth are available on special order.
