Pressure Sensor WPCK61

  • WPCK61.png


WPCK61 isolation diaphragm pressure transmitter is a high-quality general-purpose pressure measurement product with wide application. It adopts high-precision pressure-sensitive diaphragm and signal processing unit and is specially designed for conventional pressure transmitters in terms of overpressure resistance, shock resistance, ice blocking resistance, and electromagnetic interference resistance. It can be reliably used in various harsh environments for a long time. At the same time, the products also meet the relevant design requirements of explosion-proof and marine products.


* 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.
