High Accuracy Piezoresistive Diffused Silicon Pressure Sensor Core

WD19 series are based on piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. The sensing package utilizes silicon oil to transfer pressure from the 316L diaphragm to the sensing element. This digital output pressure sensor supports I2C and SPI interface protocols, may come in a 3.3 or 5.0Vdc supply voltage. 
It is designed for o-ring mounting for the applications where compatibility with corrosive media is required.A custom ASIC is used for temperature compensation, offset correction, and provides a digital output of 10~90% or 5~95%.
