Setra 2651005WDABT1C Pressure Transducer

The Setra 2651005WDABT1C is a professional-grade low differential pressure transducer engineered for precision monitoring in HVAC systems and VAV box control. This unit provides a 0 to 5" WC unidirectional pressure range, delivering highly accurate readings essential for maintaining static pressure and industrial airflow requirements. As the direct replacement for DPT2650-005D-AB, it ensures seamless integration into existing building automation systems (BAS) without needing extensive field recalibration. Featuring ±1% full scale accuracy and a robust stainless steel wetted parts construction, this sensor handles air and non-conductive gases with reliable stability.

Built for the technician, the 2651005WDABT1C utilizes a terminal strip for secure wiring and offers a 0 to 5 VDC output signal. The 24 VAC/VDC excitation provides flexibility across various controller power supplies. With its compact NEMA 1 equivalent enclosure and adjustable zero and span trim pots, this transducer simplifies commission work in cleanrooms, hospital isolation rooms, and air filtration systems. The use of capacitance sensing technology ensures long-term signal integrity and resistance to overpressure conditions occasionally found in ductwork applications.

• Direct Retrofit Compatibility: Designed as the specific DPT2650-005D-AB replacement, saving time on cross-referencing and mechanical mounting.
• Field-Serviceable Calibration: On-board zero and span trim POTs allow for precise field adjustments to match specific site conditions.
• Versatile Power Integration: Standard 24 VAC / 0-5 VDC configuration fits most commercial HVAC controllers and PLC inputs.
• Industrial Build Quality: UL94-V-0 plastic enclosure and stainless steel sensor components ensure durability in mechanical rooms and air handlers.
• High-Precision Monitoring: ±1% FS accuracy supports energy-efficient operations by providing tighter control loops for VFD fan speed modulation.

Common Questions

Is the 2651005WDABT1C compatible with older DPT264 or DPT265 series?
Yes, this model serves as a technical successor and direct replacement for the DPT2650-005D-AB, maintaining the same low differential pressure performance and 0-5V output characteristics.

Can this transducer be used for liquid pressure measurement?
While the stainless steel wetted parts offer corrosion resistance, this specific model is optimized for air and non-conductive gas media common in ductwork and pneumatic applications.

How do I handle the terminal strip wiring for a 0-5V signal?
Ensure the 24 VAC or VDC excitation is landed correctly on the identified power terminals; the signal common and 0-5V output are then wired to the controller’s analog input, utilizing the terminal strip for a secure, vibration-resistant connection.
