TMJ12 Mv Ratiometric Output Piezoresistive Anti-Corrosive OEM Pressure Sensor

TMJ12 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 Ф12.6mm. 

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