Pressure Sensor WPSK51

Summary:

WPSK51 plastic packaged pressure sensor consists of a silicon differential pressure sensor and a plastic housing. The silicon differential pressure sensor is a circuit module composed of a silicon differential pressure sensor chip and an ASIC, is packaged on an 11*11mm Al₂O₃ ceramic substrate. WPSK51 plastic packaged pressure sensor is a high-volume, low-cost civilian product, mainly used in the water treatment industry, with the characteristics of small size, light weight, compact structure, and good stability.

Feature:

* 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.
