Setra 2641010WD11T1C Pressure Transducer

The Setra 2641010WD11T1C is a industry-standard low differential pressure transducer designed for precise monitoring in building automation and critical HVAC environments. This unit features a 0 to 10" WC unidirectional pressure range, utilizing Setra’s patented stainless steel capacitive sensing element. This micro-tig welded sensor ensures superior long-term stability and resistance to overpressure up to 10 PSI. The 4 to 20 mA output provides a reliable 2-wire linear signal compatible with most energy management systems and high-end PLC controllers. Engineered for the field, the 2641010WD11T1C includes a terminal strip for secure electrical termination and 3/16” O.D. barbed brass fittings for easy integration with standard 1/4” push-on tubing. With an accuracy of ±1% full scale, this transducer is ideal for duct static pressure, filter status monitoring, and VAV fan control where air or non-conducting gas measurement is critical. The fire-retardant polyester case is UL 94 V-0 approved, and the internal regulation allows for operation with unregulated DC power supplies ranging from 9 to 30 VDC.

• High Overpressure Capability: Robust tensioned diaphragm design protects the sensor from damage during system surges up to 10 PSI.
• Standardized Output: Delivering a consistent 4 to 20 mA signal for seamless integration into existing BAS and HVAC control loops.
• Simplified Installation: Features a removable zinc-plated steel base suitable for 2.75" snap track mounting and easily accessible zero/span adjustments.
• Industrial Durability: Thermal matching of sensor components minimizes errors across operating temperatures from 0°F to 150°F.

Can this sensor be used for liquid pressure measurement?
No, this model is specifically engineered for air or dry, non-conducting gases. For liquid media, a different series with 316L stainless steel wetted parts would be required.

How do I calibrate the zero and span settings?
Calibration adjustments are conveniently located on the top of the case. Technicians can use a precision manometer and a multimeter to fine-tune the 4 mA and 20 mA points after the unit has reached thermal equilibrium.

Is this unit compatible with unregulated power supplies?
Yes, the internal voltage regulation allows the transducer to maintain accuracy even when supplied with unregulated DC power within the 9-30 VDC range.
