Application:
The T419414 water temperature sensor is engineered for the Perkins 400 Series—including 403C-11, 403C-15, 404C-22 and 404C-22T—as well as the classic 4.236, T4.236 and AT4.236 turbocharged four-cylinder diesels (4.0 L). Across agricultural tractors, combine harvesters, 40–150 kVA generator sets, tele-handlers and light construction machinery, this sensor threads into the thermostat housing or cylinder-head coolant gallery and continuously measures engine coolant temperature. The precise resistance signal it delivers to the engine control unit enables real-time adjustment of cold-start aids, fuel injection timing and electric-fan engagement, ensuring optimum combustion efficiency and emission compliance 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 falls from 9.8 kΩ ±3 % at 25 °C to 180 Ω ±10 % at 100 °C, producing 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 to achieve IP67 ingress protection. A fluoro-silicone O-ring and an integrated steel shield prevent moisture ingress during thermal cycling from –40 °C to +120 °C.
