EtherCAT Charge Amplifier PSA4

The PiezoSignalAmplifier PSA4 is a digital, 4-channel charge amplifier with EtherCAT-Interface for measuring force, tonnage, compression, acceleration, vibration, torsion with piezo electric sensors.

High-speed sampling rate and high resolution allows the evaluation of very fast processes for all types of piezo sensors.

The robust aluminum housing and the safety class IP67 allow applications of the PSA4 in rough industrial environment and guarantees a reliable and long-lasting functionality.

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