Industrial Charge Amplifier - China

price: contact company for price

Charge amplifiers convert the charge output by a piezoelectric sensor

into a proportional voltage, which is used as an input variable for

analysis systems, and can be digitized in an analog-to-digital (A/D)

converter if necessary. A charge amplifier basically consists of an

inverting voltage amplifier with a high open-loop gain and capacitive

negative feedback. It relies on a metal oxide semiconductor field effect

transistor (MOSFET) or a junction field effect transistor (JFET) at its

input to achieve high insulation resistance and minimize leakage

current. If the open-loop gain is sufficiently high, the cable and

sensor capacitance can be neglected, leaving the output voltage

dependent on just the charge at the charge amplifier input and the range

capacitor.
