025-29139 PRESSURE SENSOR TRANSDUCER YORK

025-29139 PRESSURE SENSOR TRANSDUCER YORK – Heavy-Duty HVAC & Chiller Pressure Transmitter

The 025-29139 PRESSURE SENSOR TRANSDUCER YORK (Part Series 025-29139 / Danfoss AKS 32R series OEM) is a high-precision, industrial-grade pressure transducer engineered for liquid chillers, HVAC compressors, and commercial refrigeration units. Manufactured by Johnson Controls for York systems, this ratiometric pressure transducer measures system line pressures (such as oil pressure or refrigerant pressure) and converts them into a linear DC electrical signal for continuous monitoring by MicroPanel and OptiView control boards.

Operating on a regulated 5 V DC supply voltage, the 025-29139 PRESSURE SENSOR TRANSDUCER YORK outputs a proportional 0.5 V to 4.5 V DC signal across its calibrated operational range. Built with a hermetically sealed stainless steel body, brass hex fitting, and integrated Metri-Pack connector receptacle, this transducer provides vibration resistance and moisture sealing in demanding mechanical room environments.

As shown in the product image, the sensor features a solid hex body for wrench installation, a protective rubber cap covering the threaded pressure port, a red identification label marked “YORK”, “AKS 32R”, “P : 0…275 psi”, “SUP : 5 V d.c.”, and “OUT : 0.5…4.5V”, and a black 3-pin electrical connector.

Key Features of the 025-29139 PRESSURE SENSOR TRANSDUCER YORK

• High-Accuracy Ratiometric Output: Delivers a proportional 0.5 V to 4.5 V DC analog output signal on a 5 V DC excitation voltage, ensuring low noise susceptibility.

• Calibrated 0 to 275 PSI Pressure Range: Specifically calibrated (0 to 275 PSI / 0 to 19 bar) for monitoring oil pressure differential and suction/discharge refrigerant levels.

• Hermetic Stainless Steel Construction: Robust metal body resists corrosion, refrigerant exposure, and mechanical vibration from compressor operations.

• Integrated Plug-In Wiring Harness Interface: Features a 3-pin sealed connector receptacle for quick connection to factory York wiring harnesses.

• Fast Dynamic Response: Provides real-time pressure feedback to prevent dry running, lubrication failure, and compressor trip events.

• Direct OEM Replacement: Fully compatible with legacy York pressure sensing part numbers (e.g., 025-29139-008 / 025-29139-009).

Common Applications and Practical Usage

The precision tracking capabilities of the 025-29139 PRESSURE SENSOR TRANSDUCER YORK make it essential across commercial HVAC and industrial refrigeration equipment:

• Compressor Oil Pressure Safeguard: Continuously measures compressor net oil pressure to prevent bearing damage and mechanical failure.

• Centrifugal & Screw Chiller Control: Serves as a primary feedback sensor on York YK, YT, YS, and YCAL chiller control panels.

• Refrigerant Line Monitoring: Tracks high-side or low-side pressure levels for electronic expansion valve (EEV) modulation and head pressure control.

Operating Guidelines and Installation Tips

INSTALLATION WARNING: Always isolate power and depressurize system refrigerant or oil lines prior to removing or installing pressure transducers.

• Thread Sealing: Apply approved refrigerant-compatible thread sealant to male NPT threads; do not overtighten beyond recommended torque specs (15–20 N c.m).

• Wiring Verification: Ensure correct pin assignment (5 V Power, Ground, Signal Output) on the 3-pin harness before applying control board voltage.
