A galvanic separation unit is the link in a measurement chain, which supplies power to the transducer or signal conditioning circuitry while providing galvanic isolation between the sensor-side circuitry and the power supply. It is designed for operation with charge amplifiers and signal conditioners used by piezoelectric accelerometers, dynamic pressure transducers, proximity probes and velocity sensors. An all-in-one divice: galvanic separator, power supply, current-to-voltage converter, and safety barrier
