The Setra model 239 pressure transducer is specifically designed for very low pressure applications that require high accuracy.

Setra's variable capacitance sensor is designed to be simple and reliable. A stainless steel diaphragm and an insulated electrode form a variable capacitor. As pressure increases or decreases, the capacitance changes. This change in capacitance is detected and converted to a linear D.C. electric signal by Setra's unique electronic circuit. High positive overpressure protection is achieved by the sensor electrode acting as a stop for the diaphragm. The high level output signals, excellent long term stability and fast dynamic response make these transducers ideal for a wide range of industrial, laboratory and aerospace applications.

Applications: HVAC Control, Leak Detection, Environmental Testing, Medical Instrumentation, Energy Management, Clean Rooms.
