Amplifier AQ02-010

Purpose:

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

Features:

Built-in battery with charging from an external power supply.
Power check indicators (Battery status: full charge, charging, low charge).
Low intrinsic noise.
Can be used at long communication lines (up to 100 m), almost without reducing conversion factor or limiting the low frequency region.
