Application:
The 385720101 water temperature sensor is designed for Perkins 102-04, 103-06, 103-10, 103-12, 103-13, 103-15, 104-19, 104-22, 402D-05 and 402F-05 four-cylinder naturally aspirated and turbocharged diesels, and is equally at home on the 4.236, T4.236 and AT4.236 4.0 L engines widely used across agricultural tractors, combine harvesters, 40–100 kVA generator sets, tele-handlers and light construction machinery. In these applications the sensor threads into the thermostat housing or cylinder-head coolant gallery and continuously measures engine coolant temperature, providing a precise resistance signal to the engine control unit. This allows the ECU to adjust cold-start aids, fuel injection timing and electric fan activation so that optimum combustion efficiency and emission compliance are maintained whether the engine is warming up from sub-zero or operating under sustained full load.
Technical specifications:
The unit is a brass-bodied NTC (negative-temperature-coefficient) sensor with 3/8" BSPP male thread and 22 mm hex, 58 mm overall length and 115 g mass. Its resistance decreases from 9.8 kΩ ±3 % at 25 °C to 180 Ω ±10 % at 100 °C, delivering a steep, repeatable curve that the ECU can resolve to ±1 °C.
Material & performance features:
The sensing element is a glass-encapsulated NTC bead thermally bonded to the brass probe tip for rapid heat transfer and long-term stability. The body is nickel-plated for corrosion resistance and over-moulded in high-temperature PPS resin, achieving IP67 ingress protection. A fluorosilicone O-ring and integrated steel shield prevent moisture ingress during thermal cycling from –40 °C to +120 °C.
