Setra’s Model 201 is an accurate, low cost pressure transducer for measuring very low differential of gauge pressure. Setra very low differential gauge pressure 201’s all-welded no o-ring construction results in a leak-free design, idea for the most critical low range applications. The 201 process connection is designed to be used with pressure media compatible with stainless steel and 600 Series Inconel.

Setra’s patented variable capacitance sensor design combines the ultimate in simplicity, with high accuracy and superior thermal stability. It features an Inconel diaphragm and an insulated electrode. As pressure increases or decreases, the capacitance changes. This change in capacitance is detected and converted to a fully conditioned linear current output signal. It’s rugged design, 45 PSI high overpressure capability, and wide operating temperature make the Model 201 ideal for the most demanding applications.
