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.

electronic pressure switch features

  • Adopting OLED LCD display screen, supporting Chinese and English display
  • The use of microprocessors increases flexibility and functionality
  • One analog quantity+two switching quantity dual mode outputs
  • Support two calibration methods: debugger and button; Optional two point and three point calibration modes
  • Extremely low temperature fluctuation, suitable for use in industrial environments with temperatures ranging from -30 to 80 degrees Celsius
  • Very flexible switch point setting, automatic recognition of control direction, and automatic insertion of return difference
  • Excellent anti-interference characteristics.
