Cummins 3015237 Oil Pressure Sensor Transducer

The Cummins 3015237 is an engine oil pressure sensor transducer designed to monitor lubrication system pressure in heavy-duty diesel engines. It converts oil pressure into an electrical signal for the engine control module (ECM) or gauge cluster, and incorporates a low-pressure alarm switch function. The sensor features a 1/8-27 NPT male thread for direct mounting into the engine block oil gallery. It operates on a resistive transducer principle compatible with 12V and 24V electrical systems. The pressure measurement range is 0 to 125 PSI (0 to 8.6 Bar). The integrated warning contact activates at a nominal 0.8 Bar (11.6 PSI) with a tolerance of +/- 0.3 Bar, triggering a low oil pressure shutdown or warning lamp. The housing is constructed from brass and steel alloy with a sealed connector interface, typically a 2-pin Packard Weather-Pack or equivalent double-connection terminal, resistant to vibration, oil, and temperature extremes common in mining, construction, and power generation environments. This part supersedes Cummins 5483867 and cross-references aftermarket equivalents including PAI 050637 and VDO replacements.
