A product (so-called ‘exhaust gas temperature sensor’) consisting of:
- a thermistor with a power handling capacity not exceeding 20 W, in its own housing,
- a fixing bolt,
- a shaft facilitating fixation inside a vehicle’s exhaust system,
- an electrical cable, with a heat resistant sleeve, which connects the product to a plug and which, in turn, enables connection to the vehicle’s engine management system.
Depending on the temperature, the thermistor changes its resistance. When connected, this change of resistance produces a change of electrical current, which is transmitted to the engine management system.
The product cannot convert the electrical current output into a temperature measurement or display the temperature.
