Pressure Sensor WPCH02

  • WPCH02.png


WPCH02 universal ceramic pressure transmitter is a small size, light weight, and compact pressure transmitter. It's very easy to install and use, and it's an affordable product. Self-manufactured pressure core, through reliable amplification circuit and precise temperature compensation, converts the pressure of the measured medium into a standard voltage signal output. Integrated all-stainless-steel structure and high-strength plastic components improve the overall anti-corrosion performance. Can meet pressure measurement and control demands in a variety of environmental conditions. Can be widely used in water pump, intelligent water supply, air compressor, automobile, air conditioner, water treatment, pneumatic hydraulic control, etc.


* High sensitivity, low power consumption
* Excellent stability
* Temperature Compensated, Excellent Linear Output
* Provide serial port (UART), PWM waveform and other output methods
* Long lifespan
* Anti-water vapor interference, no poisoning.
