Johnson Controls 025-29583-002 – 0 to 125 PSI Suction Pressure Transducer for York Chillers

The Johnson Controls 025-29583-002 (also cataloged under York OEM part number 025-29583-002) is a high-precision, heavy-duty suction line pressure transducer engineered specifically for commercial refrigeration and chiller equipment. Serving as a direct replacement for former part numbers such as 025-29583-001, the Johnson Controls 025-29583-002 monitors low-side refrigerant pressure across a 0 to 125 PSI operating range.

As depicted in the product image, this transducer features a stainless steel body paired with a multi-pin Packard connector and a brass pressure fitting equipped with a thread protector cap. Built to deliver regulated 0.5 to 4.5 VDC ratiometric output signals directly to York microprocessor control panels (such as OptiView and MicroPanel systems), it provides continuous feedback for superheat calculation, electronic expansion valve regulation, and low-pressure safety cutouts.

Key Features of the Johnson Controls 025-29583-002

• Calibrated 0 to 125 PSI Range: Purpose-built for low-side suction pressure monitoring in commercial HVAC and refrigeration systems.

• Voltage Output Clamping: Advanced internal electronics clamp output signals safely between 0.3 V and 4.7 V, preventing false sensor failure faults during transient temperature or pressure extremes.

• Integrated Packard Connector: Standard industrial quick-connect interface facilitates secure, weather-resistant wiring hookups in damp mechanical rooms.

• Stainless Steel Sensing Element: Constructed with a durable stainless steel process port designed to withstand continuous exposure to common synthetic lubricants and HVAC refrigerants.

• Direct OEM Backward Compatibility: Serves as a drop-in replacement for 025-29583-001, ensuring hassle-free field retrofits without requiring control board re-calibration.

Common Applications and Industrial Usage

The precise signal output and environmental seal of the Johnson Controls 025-29583-002 make it essential across commercial HVAC and industrial process cooling:

• York Air-Cooled & Water-Cooled Chillers: Installed on YVAA, YVFA, YK, and YS chiller platforms to continuously measure suction line pressure.

• Electronic Expansion Valve (EEV) Control: Relays real-time pressure data to calculation algorithms for precise expansion valve position adjustments and superheat management.

• Compressor Safety Monitoring: Provides reliable signals for low-suction safety shutdown algorithms to prevent liquid refrigerant floodback and compressor damage.

• Variable Speed Drive (VSD) Modulation: Informs capacity control logic to optimize compressor speed based on low-side refrigeration load requirements.

Installation Guidelines and Best Practices

Service Tip: Always retrieve refrigerant from the isolated compressor section and verify zero line pressure before unthreading the existing transducer.

• Flare Seal Inspection: Inspect the internal depression pin and Schrader core valve seating on the 1/4 female flare port prior to hand-tightening to prevent micro-leaks.

• Wrenching Technique: Use a backup wrench on the transducer’s hex body while torquing the flare fitting to avoid twisting the internal sensing core or damaging the connector body.

• Harness Inspection: Ensure the Packard plug rubber boot is fully seated and clicked into the transducer housing to protect terminals against ambient moisture and condensation.
