Electronic temperature and pressure (differential pressure) switch

The electronic temperature and pressure switches use electronic circuits to replace the traditional mechanical structures of switches, avoiding inherent weaknesses such as value drift, large hysteresis, low setpoint accuracy, jamming, and oxidation failure of micro-switch contacts. The electronic temperature and pressure switches utilize high-precision electrical signal sensors as signal inputs and connect to DCS/PLC systems via a two-wire system, eliminating the need for additional power supply to achieve switch functionality. The electronic switches feature a digital display and input keys, enabling visual monitoring and custom configuration of switch parameters.
