A thick-film resistive pressure transducer

Abstract A thick-film resistor pressure sensor constructed at the Pupin Institute can approach a delectability of 0.1 mbar pressure at up to 600 bar by changing only the diameter and thickness of the diaphragm. Closing the open Wheatstone bridge by a thick-film chip resistor which is soldered in the sensor cavity decreases the offset voltage (from 100 mV/10 V supply to 2 mV/10 V supply) and the influence of temperature. The accuracy of 1% FS and temperature drift of
