Setra 2651005WD2BT1C Pressure Transducer

The Setra 2651005WD2BT1C is a high-performance low differential pressure transducer engineered for precise monitoring in building automation and critical environments. This unit features a 0 to 5" WC unidirectional range and utilizes a variable capacitance sensor with a stainless steel diaphragm, ensuring long-term stability and high resistance to overpressure. Designed for standard 24 VDC power systems, it provides a stable 0-5 VDC analog output across a terminal strip connection. With an accuracy rating of ±1% Full Scale, this low pressure sensor is ideal for VAV box control, static pressure monitoring in ductwork, and cleanroom pressurized environment validation.

The compact NEMA 1 equivalent enclosure is constructed from flame-retardant UL94-V-0 plastic, making it suitable for plenum installations. The Setra 2651 series is known among field technicians for its internal zero and span adjustment POTs, which allow for easy calibration in the field without specialized equipment. The 3/16" OD barbed fittings ensure a secure fit for standard pneumatic tubing, while the reverse wiring protection prevents circuit damage during terminal block installation. This unit is built to handle inert gases and dry air, delivering a high-resolution signal to any DDC or EMS controller.

• High-Stability Monitoring: The capacitive sensing element minimizes drift and provides reliable differential pressure measurement in critical air handling systems.
• Easy Retrofit Integration: Small footprint and wall-mount design with a simple terminal strip interface simplify replacement in existing control panels.
• Durable Construction: The housing is rated for wide operating temperatures (0 to 150°F), maintaining signal integrity in demanding mechanical rooms.
• Precise Signal Output: 0-5 VDC output is compatible with most HVAC pressure sensors inputs on modern building management systems.
• Field Calibration: Integrated zero and span potentiometers allow for immediate site-specific tuning.

What is the accuracy of the Setra 2651005WD2BT1C?
