York 025-29139-004 Transducer

The York 025-29139-004 Transducer is a precision HVAC pressure sensor engineered for critical monitoring in industrial chillers, air-handling units, and refrigeration systems. As a field-proven OEM replacement part, this 0.5-4.5V ratiometric transducer converts system pressure into a stable analog signal for seamless integration with building automation systems and central controllers. Designed with a standard 1/4" NPT connection, this unit offers a reliable 0-400 PSI sensing range, providing the high-accuracy data required for maintaining optimal head pressure or suction cycles.

For technicians performing maintenance or emergency repairs, the York 025-29139-004 is cross-compatible and functionally identical to the S1-025-29139-001. Its durable construction is built to withstand the rigorous vibration and temperature fluctuations common in chiller plant environments. Replacing a faulty sensor with this genuine York pressure transmitter ensures the control board receives precise voltage feedback, preventing unnecessary system cycling and protecting the compressor from overpressure conditions. This transducer is the industry standard for maintaining the operational integrity of York and Johnson Controls equipment.

Key Benefits

• Broad Operating Range: Accurately monitors pressures from 0 to 400# PSI for high-side or low-side application versatility.
• Standardized Threading: Features a 1/4" NPT fitting for quick, leak-free installation into existing system ports.
• OEM Compatibility: Serving as a direct substitute for the S1-025-29139-001, ensuring no modifications are needed during field replacement.
• Precision Signal: Delivers a consistent 0.5V to 4.5V output, essential for accurate PLC and control board communication.
• Industrial Durability: Constructed to resist electrical noise and survive harsh mechanical room environments.

Common Questions

Is the 025-29139-004 compatible with my older York chiller?
Yes, this part is a direct replacement for the S1-025-29139-001 and is designed to interface with standard York control architectures using a 0.5-4.5V signal.

Does this transducer require a specific wiring harness?
This sensor typically uses a standard three-wire connector. If your current harness is damaged or uses an obsolete plug style, you may need a lead-wire adapter kit for a watertight seal.

Can I use this for both oil and refrigerant pressure?
While commonly used for refrigerant monitoring, this 0-400 PSI transducer is also suitable for oil pressure sensing provided the medium is compatible with the sensor's internal diaphragm materials.
