Setra 2641005WD2DT1C Pressure Transducer

The Setra 2641005WD2DT1C is an industry-standard low differential pressure transducer designed for precise air pressure monitoring in HVAC building automation and critical environments. Utilizing a dead-ended stainless steel welded capacitive sensing element, this unit provides a highly stable 0 to 5 VDC output over a 0 to 5" WC unidirectional pressure range. For contractors and technicians, the terminal strip electrical connection and 3/16” O.D. barbed brass fittings allow for rapid field installation onto standard 2.75” snap tracks or flat surfaces. This Setra 264 series sensor is engineered for long-term reliability in energy management systems, fan control, and static pressure monitoring across coils and filter banks. With ±1% full-scale accuracy and internal regulation that permits use with unregulated DC power supplies, it maintains consistent performance even in challenging electrical environments. The fire-retardant glass-filled polyester case (UL 94 V-0) and reverse wiring protection ensure hardware durability during commissioning and routine maintenance.

Key Benefits

• Precision Pressure Control: Features a capacitive sensing element with thermally matched coefficients for superior long-term stability and minimal signal drift.
• High Overpressure Capability: Built to withstand up to 10 PSI overpressure, protecting the internal diaphragm from damage during system surges.
• Seamless BAS Integration: Standard 0-5V DC analog output is compatible with nearly all modern Building Automation Systems (BAS) and VAV controllers.
• Streamlined Installation: Designed with a removable zinc-plated steel base for flexible mounting and accessible terminal strip wiring for simplified troubleshooting.

Common Questions

Can this transducer be used in bidirectional applications?
No, the 2641005WD2DT1C is a unidirectional pressure sensor specifically calibrated for a 0 to 5" WC range. For bidirectional sensing, a different configuration in the 264 series must be selected.

Is this unit compatible with unregulated power supplies?
Yes, it features internal regulation that supports excitation voltages between 9 and 30 VDC, allowing for reliable operation across various unregulated DC power leads.

What media is compatible with this sensor?
This transducer is designed for use with air or non-conducting gases. It is not intended for use with liquids or corrosive media.
