R15I-AST Sensor

Integral Preamplifier

Acoustic Emission Sensor
Description and Features

Operating Specifications

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
completely enclosed in metal stainless steel (or aluminum)
housings that are treated to minimize RFI/EMI interference.
Care has also been taken to thermally isolate the critical
input stage of the preamplifier in order to provide excellent
temperature stability over the range of -35º to 75º C.

Their integrated Auto Sensor Test (AST*) capability allows
these sensors to pulse as well as receive. This feature lets
you verify the sensor coupling and performance at any time

Applications
This general purpose sensor provides a good mix of high
sensitivity and high low frequency rejection. These properties make it 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 monitoring applications. It is
PAC’s most popular and highest volume selling sensor.

* AST — Auto Sensor Testing feature allows AE systems to control the sensor as a pulser
and a receiver at the same time. It can therefore characterize its own condition as well
as send out a simulated acoustic emission wave that other sensors can detect, so the
condition of the nearby sensors also can be tested.
