Features
SS307 series ceramic diaphragm pressure transmitter is designed based on the ceramic cell (Al2O3 96%). The pressure sensor works following the piezoresistive principle. The signal conditioning electronics are on one side of the ceramic diaphragm. The Wheatstone bridge is screen printed there. It offers a 4-20mA current output or voltage signal. The housing is made from stainless steel with internal O-ring seals. This design makes the product fit for many applications.
Because of the ceramic material, SS307 series has excellent chemical immunity and is suitable for nearly all media.
Typical applications include:
Pressure calibration
Compressors
Dispensers
Refrigerators
Locomotive braking systems
Hydraulic and pneumatic equipment
Industrial process measurement and control
