Setra 2641005WD11A1C Pressure Transducer

The Setra 2641005WD11A1C is the industry-standard low differential pressure transducer, engineered specifically for building automation and mission-critical HVACR applications. This unit features a 0 to 5" WC unidirectional pressure range and provides a precise 4 to 20 mA output signal. It utilizes Setra’s signature all-stainless steel micro-tig welded capacitive sensing element, which ensures ±1% FS accuracy and exceptional long-term stability even in demanding environments. Designed for efficiency, the 1/2" conduit enclosure protects internal components and simplifies wiring for professional installers. This model is functionally identical to the DPT2641-005D-1, offering a reliable drop-in solution for VAV box control and air flow monitoring. With a robust design capable of withstanding up to 10 PSI overpressure, the Setra 264 series maintains calibration integrity throughout the life of the system. For contractors managing energy management systems, this transducer delivers the high-level analog signal required for precise duct static pressure control.

• High Accuracy Sensing: Features ±1% full scale accuracy using an advanced capacitive sensing element for stable low pressure measurement.
• Rugged Reliability: Built with a fire-retardant glass-filled polyester case (UL 94 V-0) and 10 PSI overpressure capability to prevent damage from line spikes.
• Universal Compatibility: Standard 4-20mA 2-wire loop output integrates seamlessly with most building controllers and BAS platforms.
• Simplified Installation: 1/2" conduit electrical termination and 3/16" dual barb fittings facilitate fast mounting in new or retrofit projects.
• Field Proven: Trusted in over 8 million installations worldwide for clean room pressurization and hospital critical environment monitoring.

Is the Setra 2641005WD11A1C a direct replacement for the DPT2641-005D-1?
Yes, the 2641005WD11A1C is the exact technical equivalent and direct replacement for the DPT2641-005D-1, maintaining the same 0-5" WC range and electrical characteristics.

Can this transducer be used with liquids?
No, this unit is designed strictly for use with clean air or non-conducting gases. Exposure to liquids or corrosive media will damage the capacitive sensor.

What power supply is required for the 4-20 mA output?
This is a 2-wire loop-powered device that operates on 9 to 30 VDC. It was factory calibrated with a 24 VDC supply and a 250-ohm load for optimal performance.
