Application:
The U85246210 oil pressure sensor is engineered for Perkins
403D-07, 403D-11, 403D-15, 403D-17, 404D-15, 404D-22, 404D-22T,
1103D-33, 1103D-33T, 1104D-44, 1104D-44T and 1106D-E70TA
turbocharged four- and six-cylinder diesels. These engines power
compact agricultural tractors, combine harvesters, 40–150 kVA
generator sets, tele-handlers, skid-steer loaders and light
construction machinery. In these applications the sensor
continuously monitors main-gallery oil pressure and transmits a
real-time 0–5 V analogue signal to the engine control unit. Should
pressure drop below the calibrated safety threshold, the ECU
immediately illuminates a warning lamp and can derate or shut down
the engine to protect crankshaft bearings, turbochargers and
high-pressure fuel pumps from catastrophic damage.
Technical specifications:
The unit is a three-wire piezo-resistive pressure transducer housed
in a brass body with a 1/8" NPTF male thread and 19 mm hex. It
measures 0–10 bar (0–145 psi) with ±2 % full-scale accuracy,
outputs a linear 0.5–4.5 V signal referenced to a 5 V supply and
draws less than 10 mA at 12 V. Operating temperature spans –40 °C
to +125 °C and the sensor withstands 1 000 h salt-spray exposure
per ASTM B117.
Material & performance features:
The sensing diaphragm is 17-4 PH stainless steel, laser-welded to
the brass body for absolute hermetic sealing and protected by a
sintered brass snubber that damps pressure pulsations and prevents
oil-borne debris from reaching the element. Internal circuitry is
over-moulded in high-temperature PPS resin, achieving IP67 ingress
protection and surviving 500 thermal-shock cycles from –40 °C to
+125 °C without calibration drift.
