HBM PX455 - PX401 with Charge Amplifier

PMX A4354-2.2 HBM: public 83
8.4.3.5 PX401 with charge amplifier
Piezoelectric sensors can be operated with the PX401 via
external CMA or CMD charge amplifiers. The charge
amplifiers convert the sensor signal into a +/-10 V voltage
signal. The reset/operate charge amplifier signal can take
place in the PMX from an external controller or via a
PX878 digital output. The CMA charge amplifier can be
supplied directly by the PX401 measurement module.
Important
Due to the inrush current of the CMD charge amplifier,
the current feed of the CMD must be separate and not via
the PX401 measurement module.
