Product Description

The 131S is a silicon piezoresistive pressure transmitter fitting most industrial pressure measurement applications. Thanks to its compact and rugged design, this model is suitable for applications of processing and control operations such as hydraulics, pneumatics, test equipment, liquid level measurement, compressor and pump control, etc. With various options of process connection and electrical interface, the 131S can be fitted into almost all common systems.

The 131S consisting of a stainless steel diaphragm, wetted part, and housing can be used for measurements involving hostile media compatible with 316 stainless steel. Featuring an inner-cavity process connection, the transmitter is specially designed to measure pressure of gases or dilute fluids with pressure reference of gauge, absolute, or sealed gauge.

By selecting proper electrical interface, the 131S is able to reach the environmental protection rating up to IP67.
