Acoustic preamplifier / for sensors

The 0/2/4 and 2/4/6 Preamplifiers were designed to be used with all available AE systems that have their power supplied via the output signal BNC. Provided with 0/20/40 and 20/40/60 dB gain (switch selectable), respectively, these preamplifiers operate with either a single-ended or differential sensor. Plug-in filters provide the flexibility to optimize sensor selectivity and noise rejection. These filters are supplied in the Low Pass (LP), High Pass (HP) and Band Pass (BP) configurations, and offer constant insertion loss for easy filter swapping without the need for recalibration. The standard Auto Sensor Test (AST) allows the sensor to characterize its own condition, as well as send out a simulated acoustic emission wave that other sensors can detect.
0/2/4 Features:

* Wide dynamic range * Low noise * Large output signal - 20Vpp into 50 ohms
* Single power/signal BNC or optional separate power/signal BNC
* Plug-in filters
* 0/20/40 selectable gain
* High input impedance
* Standard auto sensor test (AST)
* Input protection


2/4/6 Features:
* Wide dynamic range * Low noise * Large output signal - 20Vpp into
50 ohms
* Single power/signal BNC or optional separate power/signal BNC
* Plug-in filters
* 20/40/60 selectable gain
* High input impedance
* Standard auto sensor test (AST)
* Input protection
