Setra Systems Model 204D pressure transducer is intended for accurate differential pressure measurement of gas or liquid media compatible with 17-4PH stainless steel. The high level output signal and excellent stability, combined with fast dynamic response, make this unit ideal for industrial, laboratory, and aerospace applications requiring the highest accuracy. The 204D is thermally compensated for both zero and span shifts due to environmental temperature variations. Setra’s unique high output electronic circuitry requires no additional signal conditioning.

Setra’s patented variable capacitance sensor approaches the ultimate in design simplicity. It features a one-piece 17-4PH stainless steel pressure sensor and an insulated electrode, which form a variable capacitor. As pressure increases, the capacitance decreases. This change in capacitance is detected and converted to a linear DC signal by Setra’s unique electronic circuit.
