KFP70 electronic pressure switch is a pressure measurement and control product integrating pressure measurement, output and control. The front end of the product adopts an oil-filled pressure sensor with an isolation film. The output signal is amplified by a high-precision, low-temperature drift amplifier. The signal processed by the operation controls the 1-way or 2-way switch to measure and control the pressure of the control system.
