Model 201 Low Differential & Gauge Pressure
Brand: Setra Systems, IncSetra’s Model 201 is an accurate, low cost pressure transducer for measuring very low differential of gauge pressure.
The 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.
