Amplifier AQ08

Purpose:

Converting high-impedance charge signal from piezoelectric transducers to a low-impedance voltage signal.

Features:

Low intrinsic noise.
Can be used at long communication lines (up to 100 m), almost without reducing sensitivity or limiting the low frequency region.
Normalization mode.
Measurement report.
Operating mode control via RS-485 port with an option of connecting up to 128 amplifiers.
