Descriptions

SS309 series differential pressure sensor is very rugged and designed for use as a wet/wet differential pressure transmitter, it can be used to measure gas or liquid pressure compatible with stainless steel wetted parts and viton. A high performance piezoresistive differential pressure transducer is sealed by O-ring inside as the pressure sensing element, silicone oil is filled in the transducer housing between the silicon chip and stainless steel 316L diaphragm, the measured pressure act on the silicon chip through the diaphragm and silicone oil.

SS309 series has two pressure ports for high and low pressures, the output signal generated by the piezoresistive bridge sensor is amplified into a useable voltage or 4-20mA output signal, it comes in a variety of mechanical and electrical configurations, is ideal for differential pressure measurement of petroleum, chemical industry, power station and also used for flow measurement.
