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)

you verify the sensor coupling and performance at any time
throughout the test.

* 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.
