Setra 26412R5WB11T1C Pressure Transducer

The Setra 26412R5WB11T1C is a professional-grade low differential pressure transducer engineered for precision measurement in HVAC building automation and critical environmental controls. Built with an all-stainless steel, micro-TIG welded capacitance sensing element, this unit provides exceptional long-term stability and resistance to mechanical shock. It features a ±2.5" WC bidirectional pressure range, allowing for accurate monitoring of both positive and negative pressures relative to a reference point, making it ideal for room pressurization and VAV fan control applications.

Operating on a standard 2-wire 4 to 20 mA output circuit, the 26412R5WB11T1C is designed for seamless integration with most energy management systems. The ±1% FS accuracy ensures reliable performance in demanding healthcare and pharmaceutical facilities. For simplified installation in the field, it includes a terminal strip electrical connection and is housed in a UL 94 V-0 fire-retardant case. This model supports up to 10 PSI overpressure, protecting the internal stainless steel diaphragm from damage during system surges or improper duct balancing.

• Enhanced Stability: The capacitive sensing technology minimizes signal drift, ensuring NIST traceable calibration remains consistent over time.
• Robust Overpressure Protection: Rated for up to 10 PSI overpressure, preventing sensor failure during high-velocity startup or filter blockages.
• Easy Installation: Features a terminal strip and a compact design compatible with standard 2.75" snap track mounting.
• Media Compatibility: Optimized for use with clean air or non-conducting gases in sensitive air-handling applications.

Is the Setra 26412R5WB11T1C compatible with unregulated power supplies?
Yes, the internal regulation allows this transducer to operate reliably on unregulated DC power supplies between 9 and 30 VDC.

What is the proper output for a bidirectional range?
For this bidirectional unit, the factory-set zero pressure output is 12 mA, providing a linear signal across the ±2.5" WC range.

Can this unit be used for liquid pressure sensing?
No, this model is specifically designed for differential air pressure and non-conducting gases. Contact our team for liquid-compatible wet-to-wet transducers.
