WESPC Oil Pressure Sensor U85246210 For Perkins Engine 404D-22 404C-22 403D-17

Application:

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.
