The R15a is a narrow band resonant sensor with a high sensitivity. The sensor cavity is machined from a solid stainless steel rod, making the sensor extremely rugged and reliable. The ceramic face along with a 30 degree chamfer to cavity electrically isolates the sensor cavity from the structure under test assuring a low noise operation.

Incorporating a low-noise input, 40 dB preamplifier and a filter all inside the sensor housing, these transducers are completely enclosed in metal stainless steel (or aluminum) housings that are treated to minimize RFI/EMI interference.

-frequency rejection. These prop-erties make the sensor very useful for monitoring common structures such as pipelines, vessels, bridges, and storage tanks in petroleum, refineries, chemical plants, offshore platforms, as well as factory and process mo. esponse of the R15α. Calibration based on ASTM E1106; Calibrat. .............

PAC’s integral preamp sensors were specifically engineered to attain high sensitivity and have the capability to drive long cables without the need for a separate preamplifier. Incorporating a low-noise input, 40 dB preamplifier and a filter all inside the sensor housing, these transducers are

R15I-UC/R15-UC is an underwater, narrowband sensor with very high sensitivity in the frequency bandwidth 50 – 400 kHz. The sensor features two versions one with an integral preamplifier with 40 dB gain (R15I-UC) and one without (R15-UC).
