Introduction of Pressure Sensor

PSJ30 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. 

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

Special features of Pressure Sensor

·Wet parts and sealing apply stainless steel welding realize an excellent anti corrosion

·Gauge, Sealed Gauge 

·10VDC or Idd=1.5mA excitation 

·Output ratiometric mV signal, customized I2C or SPI Output 

·PCB potting is optional

·Silicon oil filling sensor element
