Setra 230 Wet Differential Pressure Transducer

Setra Systems Model 230 is a high output, low differential pressure transducer designed for wet to wet differential pressure measurements of liquids or gases. A fast-response capacitance sensor and signal conditioned electronic circuitry provide a highly accurate, linear analog output proportional to pressure. Both unidirectional and bidirectional pressure ranges are available for applications with line pressure up to 250 psig.

This wet to wet differential pressure transducer provides a high output without compromising your budget. Unlike fluid filled sensors that can rupture, the Model 230's wetted parts are all stainless steel. Unidirectional and bi-directional ranges are available from ±1 to 100 psid, and choice of 0 to 5 VDC or 0 to 10 VDC, or 4 to 20 mA output.

Select From Available Ranges:

Output Options: 4-20 mA Output
0-5 VDC Output
0-10 VDC Output
Fitting Options: Standard 1/4 Inch NPT (F) Pressure Fitting
Optional 3-Valve Manifold Assembly
