Bosch Motorsport | Temperature Sensor NTC M12-L

Temperature Sensor NTC M12-L

 Application: -40 to 130°C
 Accuracy at 25°C: ± 1.4°C
 Accuracy at 100°C: ± 3.4°C
 Male thread: M12 x 1.5
 Nominal resistance: 2.5 kOhm ± 5 % (at 20°C)

This sensor is designed to measure air temperaturee.g. in the air box or ambient temperature. This signal may be used as a control value for engine control
units or as a measurement value which is logged in adata acquisition system.
The NTC sensing element has a negative temperature coefficient. This means, that with increasing temperature the conductivity rises. The sensing elementof the temperature sensor is made of semiconducting heavy metal oxide and oxidized mixed crystals,
which are equipped with a protective housing.
The main benefit of the sensor is the combination ofa high quality production part and a robust and compact design.
