Electronic pressure switch (EPS) is designed to signal the measured pressure value (absolute or gage) and convert it to a unified switching signal. The principle of operation of the pressure switch is that pressure is applied to the input, and the sensitive element (strain gauge transducer) fed from a stabilized current source changes its resistance depending on the applied pressure and then the output voltage is converted by an instrumentation amplifier. EPS can be widely used in systems of automatic control, regulation and management of technological processes in various industries.
