Setra 2641003WD11T1C Pressure Transducer

The Setra 2641003WD11T1C Pressure Transducer is the industry-standard solution for technicians requiring high-precision low differential pressure monitoring in critical environments. Engineered with a unidirectional pressure range of 0 to 3 in WC, this unit utilizes an all-stainless steel micro-tig welded capacitive sensing element. This advanced design ensures exceptional long-term stability and a consistent 4 to 20 mA output, making it ideal for integration with building automation systems and energy management controllers. The rugged fire-retardant case is UL 94 V-0 approved, housing a ±1% FS accuracy sensor that maintains performance despite fluctuations in environment temperature or line pressure.

For ease of field installation, the Setra 1003WD features a terminal strip electrical connection and 3/16-inch brass barbed fittings compatible with standard 1/4-inch push-on tubing. Internal regulation allows the transducer to operate on unregulated DC power supplies between 9 and 30 VDC, while integrated reverse wiring protection safeguards the electronics during commissioning. Whether managing static pressure in VAV boxes or maintaining room pressurization in healthcare facilities, this 0-3 inch water column sensor provides the reliability veteran contractors demand for HVAC/R and pharmaceutical applications.

• Enhanced Stability: Proprietary capacitive sensing technology reduces the need for frequent recalibration in long-term installations.
• Overpressure Protection: Robust sensor design handles up to 10 PSI overpressure without compromising accuracy or calibration.
• Fast Installation: Features a removable zinc-plated steel base and easy-to-access terminal strip for rapid wall or snap-track mounting.
• Wide Compatibility: Standard 4-20mA current loop signal is compatible with almost all industrial PLC and BAS inputs.

• What tubing is recommended for the 3/16" barbed fittings? For optimal response time, use 3/16" I.D. tubing for runs under 100 feet. For longer runs up to 300 feet, 1/4" I.D. tubing is suggested with appropriate adapters.
• Can this unit be mounted in any orientation? While the sensor can be mounted in various positions, it is factory-calibrated in the vertical position. Mounting it horizontally may require a simple zero-adjustment to compensate for positional effects.
• Is the 2641003WD11T1C suitable for liquid media? No, this transducer is designed strictly for clean air or non-conducting gases. Use with liquids or corrosive gases will damage the capacitive element.
