It detects oil pressure and sends a signal to the ESP-100 control, enabling alarm or shutdown when pressure is low. The sensor is a direct replacement for the original part.\u003c\/p\u003e\u003ch4\u003eOverview\u003c\/h4\u003e\u003cp\u003eThis oil pressure sensor for Murphy ESP-100 replaces the 05-70-1857 sender, providing reliable pressure feedback for engine shutdown protection. It is a single-wire device that connects directly to the ESP-100 controller, translating oil pressure into a measurable electrical signal. The sensor suits engines equipped with Murphy ESP-100 safety panels.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle wire design simplifies wiring and troubleshooting\u003c\/li\u003e\n\u003cli\u003eRugged construction withstands engine heat and pressure pulses\u003c\/li\u003e\n\u003cli\u003eDirect fit for Murphy ESP-100 controller inputs\u003c\/li\u003e\n\u003cli\u003eOEM cross-reference numbers 05-70-1857 and 05701857\u003c\/li\u003e\n\u003cli\u003eThreaded fitting allows secure mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Murphy ESP-100 engine protection panels\u003c\/li\u003e\n\u003cli\u003efor Murphy ESP-100 series controllers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInstalled on engine oil galleries for continuous pressure monitoring\u003c\/li\u003e\n\u003cli\u003eCommon in generator sets and compressor units\u003c\/li\u003e\n\u003cli\u003eUsed in agricultural irrigation engines with ESP-100 controls\u003c\/li\u003e\n\u003cli\u003eApplied in oilfield pumping engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e05-70-1857, 05701857\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnection Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSingle Wire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible System\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMurphy ESP-100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOil Pressure Sensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How do I know if this sensor matches my Murphy ESP-100 setup?\u003cstrong\u003eA:\u003c\/strong\u003e Check that your existing sender has the same part number or cross-reference and that your controller uses a single-wire sender input.
