Application:
The 2874A002 temperature sensor is developed for Perkins 1104C-44T,
1104C-E44, 1104C-E44T, 1104C-E44TA and 1106C-E60TA turbocharged
four- and six-cylinder diesels, and is equally compatible with the
403C-11, 403C-15, 404C-22 and 404C-22T family engines. These power
units are widely used across Massey Ferguson 5465, 6460, 6465,
6470, 6475, 6480, 7465, 7475 and 7480 agricultural tractors,
combine harvesters, 40–150 kVA generator sets, tele-handlers,
backhoe loaders 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
ECU. This enables the ECU to control cold-start aids, fuel
injection timing and electric fan engagement 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, 56 mm overall
length and 99 g mass. Its resistance falls 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 between –40 °C and
+120 °C.
