Digital charge amplifier PSA4T

The Piezo Signal Amplifier PSA4T is a digital 4-channel charge/temperature amplifier with integrated multi-protocol 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 combination of charge and thermocouple amplifiers makes the amplifier particularly suitable for use in the injection molding industry and mechanical engineering.

The integrated thermocouple measuring amplifiers are suitable for type J or K thermocouples.

They have wire break detection and are already calibrated at the factory. The measured value is output (configurable) in °K or °C. A "substitute value" or error value can be configured for wire break detection.

The robust aluminum housing and IP67 protection class allow the PSA4T to be used in harsh industrial environments and guarantee reliable and durable functionality.

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

The multiprotocol fieldbus interface allows all Ethernet-based fieldbuses such as EtherCAT/Profinet/POWERLINK/Ethernet IP as well as Profibus to be used. The desired fieldbus can be easily (pre-)set by the customer using a code switch or configuration via the diagnostic interface.
