SPI I²C 0.5-4.5V Diezoresistive Pressure Sensor

Details

Introduction

 

WD19 series is a 14-bits digital output pressure sensor, supporting I²C interface protocol. The external pressure is passed to sensitive elements through 316L stainless steel diaphram and internal silicon oil. Thus D10 sensors can be used to measure all pressure media compatible with 316L stainless steel.

The series sensor realizes pressure and temperature calibration and compensation via a specially customized integrated circuit. It outputs 10%-90% digital signal as well as digital output of temperature signal.
