Piezo Amplifier (charge amplifier)

Piezo Amplifier is designed for use together with the PD-4 / PD-6 transducer. It is used to amplify the signal from the piezo transducer. The output signal of a piezo sensor is not voltage or current, but charge. Therefore, the signal of such a transducer first enters the charge amplifier, where it is converted into voltage, and only then is it connected to the oscilloscope input.
