Charge amplifier


Thread Starter

Mark Vyshkin

We are going to use a piezo sensor with a charge amplifier to measure turbulence in liquids. The problem is that the liquid is earthed and we get
a lot of 50 Hz noise. To solve the problem we need a charge amplifier with galvanically isolated differential input. Has anybody heard of such devices ? Maybe, some references.
Thanks in advance.
