Introduction of Pressure Sensor

TMC12 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 ratio linear electric signal.

Special features of Pressure Sensor

·1.5mA or 5VDC excitation 

·mV ratio output signal

·Full scale output 40mV(min)

·PCB potting is optional

·Wet parts apply all stainless steel welding excellent corrosion resitance

·Silicon oil filling
