Amplifier GT500B-01

Purpose:

Receiving and amplification of signals from acoustic emission sensors to normalized values.

Features:

Can be used at long communication lines (up to 10 m) from sensor to amplifier.
Can operate on coaxial 50 Ohm line with a length of up to 100 m.
Switching amplification factor via RS-485 interface or by closing Kus contacts located under the amplifier cover (amp factor round-robin).
Connection of sensors with balanced output.
GT500B-01 has additional low-frequency output to measure vibration acceleration of monitored objects.
Mounted on a 35mm DIN- rack.
Waterproof casing.
