Introduction of Pressure Sensor

TMC19 pressure sensor is piezoresistive silicon pressure sensor with isolated construction and precise high low temperaure compensation, build-in high stable silicon chip, stainless steel 316L housing by diameter Ф19mm. 

Design concept base on wheatstone bridge principle, the measured pressure cause resistance bridge value variation, then it converted to ratio linear electric signal.
