Setra Model 239 Pressure Transducer

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 for the Setra Model 239:

• HVAC Control
• Leak Detection
• Environmental Testing
• Medical Instrumentation
• Energy Management
• Clean Rooms
