The main functions of the PW222 electronic pressure switch measurement and control transmission product include 4-20mA transmission output, two-way relay switching output, and on-site display function. Adopting SMT technology and integrated design concept, the sensor can provide constant voltage excitation, constant current excitation, and adapt to diffusion silicon, ceramics, and strain type pressure sensors Its built-in microprocessor can realize the adjustable setting of zero point, full range, Decimal separator and control point and current setting without any Potentiometer adjustment through three key programming. The entire machine is suitable for industrial temperature environments and has strong anti-interference capabilities.
