Electrohydraulic pressure regulator has several pressure sensors, each with pressure measurement membrane, electrically passive measurement transducer with no calibration device

摘要

The device has integrated pressure sensors for detecting the pressure of a fluid in pressure lines. There is a valve block and an electronic regulator combined via a magnetic plug to form a compact sealed unit with a hollow volume containing several pressure sensors (16). Each sensor contains a pressure measurement membrane (32) and an electrically passive measurement transducer (33) with no signal calibration device. AN Independent claim is also included for an error compensation method, especially for a pressure regulator.
