What is the difference between a piezoelectric sensor with charge (PE) or voltage (IEPE) output?
For piezoelectric pressure sensors, one of the most important selection criteria is the output signal. Piezoelectric pressure sensors are connected to an electronic circuit which converts the charge generated by the sensor into a proportional voltage. If the electronics is an external device (charge amplifier), it is referred to as charge output or PE sensor. If the electronic circuit is integrated into the sensor housing, then it is referred to as a voltage output or IEPE sensor.
