Setra 2641025WD11T1C Pressure Transducer

The Setra 2641025WD11T1C is a high-reliability low differential pressure transducer engineered for precision monitoring in critical HVAC and building automation environments. Designed for a 0 to 25" WC unidirectional pressure range, this unit utilizes an 11-T1 terminal strip for secure wiring and provides a standard 4 to 20 mA output signal. Field technicians prefer the Model 264 for its rugged construction and stable capacitive sensor technology, which maintains ±1% FS accuracy even in variable air volume (VAV) applications. The Setra 264 series is a staple for static pressure sensor installations in ductwork and cleanrooms where long-term stability is non-negotiable. Its compact footprint and mounting bracket allow for efficient installation in tight control panels, while the differential pressure transmitter design ensures reliable feedback for air velocity and environmental control systems. Whether managing HVAC pressure monitoring or industrial air flow, this transducer delivers the repeatable performance required for commercial commissioning.

• Industrial Stability: Employs a patented variable capacitance sensor for long-term signal integrity and minimal zero shift.
• Standardized Integration: The low pressure transducer features a 4-20 mA current loop that is compatible with most BMS and PLC controllers.
• High Overpressure Protection: Rated to withstand significant overpressure without damage or recalibration requirements.
• Easy Field Wiring: Equipped with a terminal strip and 3/16-inch barbed fittings for quick connection to draft pressure sensor tubing.

How do I calibrate the zero point on the Setra 264?
Technicians can access the zero and span potentiometers on the top of the unit; ensure no pressure is applied before adjusting the zero signal to 4 mA.

Can this unit be mounted in any orientation?
While it can be mounted in various positions, it is factory-calibrated in a vertical position. Mounting it horizontally may cause a slight zero shift that must be compensated for during commissioning.

Is the 11T1C terminal strip suitable for outdoor use?
The Model 264 is designed for indoor NEMA 1 environments; for rooftop or high-moisture areas, it must be housed within a secondary NEMA 4 rated enclosure.
