Amplifier AQ07-01

Purpose:

Converting high-impedance charge signal from a piezoelectric transducer (vibration transducer, force sensor, dynamic pressure sensor, etc.) 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.
Overload indication.
Operating mode control via USB port.
