Applications of Pressure Transducer

·Measure and control of petroleum          


·Pharmaceutical manufacturing

·Food processing industry

Introduction of Pressure Transducer

PT50 pressure transducer has the pressure chamber which is made of single complete stainless steel piece, and all-metal sealing structure. Stainless steel flush diaphragm can effectively present clogging.The pressure transmitter uses ORR's silicon oil filling technology and has specially designed structure. It adopts the overall digital calibration and temperature compensation.PT50 pressure transducer widely used in food processing industry.  

Special features of Pressure Transducer

·Wetted parts apply stainless steel ensure excellent corrosion resitance

·EMC, temperature, humidity test

·IP65 protection

·Ex-proof ExiaⅡCT6 certification
