YORK 025-28678-001 Danfoss Pressure Transducer

025-28678-001 is the original part number of York (a brand under Johnson Controls). The standard description is Pressure Transducer (pressure sensor / pressure transducer). In the "Pressure Transducer Application Table" of the "OptiView YK" service manual, this part number corresponds to the function of High Oil (high oil pressure), which is installed on the oil supply circuit of the compressor to convert oil pressure into an electrical signal and send it to the control center for monitoring and protection - ensuring the establishment of sufficient oil pressure, alarming or stopping when the oil pressure is abnormal, and preventing the bearings and gears from being damaged due to lack of oil.
Key specifications: Range 0–300 PSI; Pressure interface is 1/4" external thread NPTF (the manual clearly states that 025-28678-001, -004, -102, -103, -104 are NPTF conical pipe threads, while -006, -112, -113, -114, 025-39464-000, 025-40088-000 are straight threads with O-ring, the two types cannot be mixed); Shape approximately 4.4 × 4.4 × 4.4 inches; Origin United States.
Relationship with Danfoss: This part is manufactured by Danfoss, corresponding to the AKS 32 series pressure transducers (the domestic channel often marks the Danfoss code 060G1485, and the typical specifications of AKS 32 are 1–5 V DC output, 9–32 V DC power supply, accuracy ±0.3% FS typical / ±0.8% FS maximum, IP65, medium temperature -40 to +85℃). Due to different part numbers of York corresponding to different ranges and output calibration, AKS 32 is only a series name, the specific range must be checked in the table according to the part number.
