Setra 26412R5WD11T1C Pressure Transducer

The Setra 26412R5WD11T1C is an industry-standard low differential pressure transducer designed for precise HVAC building automation and critical environment monitoring. This unidirectional pressure sensor features a 0 to 2.5" WC (Water Column) range and utilizes Setra’s patented stainless steel capacitive sensing element. This all stainless steel micro-tig welded sensor provides superior long-term stability and resistance to overpressure up to 10 PSI. Engineered for seamless integration into Energy Management Systems, it delivers a linear 4 to 20 mA output via a secure terminal strip electrical connection. With a ±1% FS accuracy rating, this differential air pressure sensor is ideal for duct static pressure measurement, VAV fan control, and laboratory fume hood monitoring. The compact housing supports snap track mounting, while the dual 3/16” barbed brass fittings ensure reliable pneumatic connections in demanding mechanical room applications.

Key Benefits

• Reliable static pressure monitoring with high resistance to overpressure damage.
• Optimized for VAV system control and building pressurization accuracy.
• NIST traceable calibration ensures professional-grade measurement precision.
• Internal regulation supports use with unregulated DC power supplies (9-30 VDC).
• Specifically built for non-conducting gas and dry air HVACR applications.

Common Questions

How do I wire this pressure sensor for a 4-20mA loop?
This model uses a two-wire current loop. Connect the positive supply to the (+) terminal and the return to the (-) terminal. The unit is factory-calibrated at 24 VDC for maximum accuracy across the 4 to 20 mA range.

Is the Setra 26412R5WD11T1C suitable for wet media?
No, this HVAC pressure transducer is designed for dry air and non-corrosive gases only. Exposure to liquids or corrosive media will damage the capacitive sensing diaphragm.

Can this unit be mounted in any orientation?
While it can be mounted in various positions, it is factory-calibrated in the vertical position. Mounting it horizontally may cause a slight zero-shift, which can be corrected using the onboard zero-adjustment potentiometer.
