Temperature sensors

Sensors represent the interfaces between the ECU, as a processing unit, and the vehicle, with its complex drive, braking, chassis and bodywork functions. The field of mechatronics, in which mechanical, electronic and data processing components are interlinked and cooperate closely with each other, is rapidly gaining in importance in the field of sensor engineering. Since their output signals directly affect not only the engines power output, torque and emissions, but also vehicle handling and safety, sensors, although becoming smaller and smaller, must also fulfil demands that they be faster and more precise.

Applications:

Engine Temperature Sensor

This sensor is installed in the coolant circuit. The engine management system uses its signal when calculating the engine temperature. The measuring range is usually from -40° to + 130°C.

Air temperature sensor

This sensor is installed in the air intake tract. Together with the signal from the manifold absolute pressure sensor, its signal is applied in calculating the intake air mass. Apart from this, desired values for the various control loops can be adapted to the air temperature. The measuring range is usually from -40° to + 120°C.

Engine oil temperature sensor

The signal from this sensor is used in calculating the service interval. The measuring range is usually from -40° to + 170°C.

Exhaust gas temperature sensor

This sensor is mounted on the exhaust system at a point which is particularly critical regarding temperature. It is applied in the closed loop control of the systems used for exhaust gas treatment. A platinum measuring resistor is usually used. The measuring range is usually from -40° to + 1000°C.
