Setra 2651006WD11A1C Pressure Transducer

The Setra 2651006WD11A1C is a professional-grade low differential pressure transducer engineered specifically for high-efficiency HVAC system monitoring and VAV fan control. This unit features a 0 to 6 in. W.C. range and utilizes Setra’s signature all-stainless steel capacitive sensing element. Unlike cheaper alternatives that rely on signal amplification, this dead-ended sensor design minimizes thermal drift and hysteresis, ensuring ±1% FS accuracy across its service life. The 2-wire 4 to 20 mA loop-powered output facilitates seamless integration with building automation systems (BAS) and energy management systems. Built for the field, the housing includes a 1/2-inch conduit enclosure and reverse wiring protection, allowing for straightforward installation by service technicians in tight mechanical spaces. Whether you are balancing airflows in cleanroom pressure monitoring or measuring static duct pressure, this transducer delivers the rugged reliability and long-term stability required for critical environment management without unnecessary complexity.

• Enhanced Accuracy: The capacitive transduction principle provides a stable 1% full-scale accuracy, improving variable air volume (VAV) efficiency.
• Rugged Housing: Equipped with a UL 94 V-0 fire retardant case and a Lexan conduit cover for secure electrical termination.
• Simple Commissioning: Features accessible Zero and Span potential pots and integral mounting tabs to reduce onsite labor time.
• Broad Compatibility: Operates on standard 24 VDC excitation and is designed for use with air or non-conducting gases.
• Internal Regulation: Allows for reliable performance even when powered by unregulated power supplies.

How do I troubleshoot a low or missing output signal?
First, verify your loop power supply is providing between 9 and 30 VDC. Check for incorrect polarity or multiple grounds in the circuit. If the unit is still unresponsive, disconnect the signal wire and measure the 4 mA baseline at zero pressure to confirm the sensing element is intact.

Can this transducer be used in liquid applications?
No, this model is specifically designed for air and non-conducting gas media. Introducing liquids or corrosive gases will cause permanent damage to the stainless steel sensor components.

Does the mounting orientation affect the calibration?
While the 265 is factory-calibrated, mounting it in a non-vertical position can cause a slight zero shift on ranges below 1" W.C. Always perform a final zero adjustment using the front-facing trim pot after the unit is permanently mounted.
