Digital charge amplifier PSA4eC

The Piezo Signal Amplifier PSA4 is a digital 4-channel charge amplifier with integrated EtherCAT fieldbus interface for measuring force, tonnage, pressure, acceleration, vibration and torsion using piezoelectric sensors.

The high sampling rate and high resolution enable the evaluation of very fast processes for all types of piezo sensors.

The robust aluminum housing and IP67 protection class allow the PSA4 to be used in harsh industrial environments and guarantee reliable and durable functionality.

The low drift of the input stages and the digital processing of the charge signal are very precise and therefore also allow quasi-static measurements.
