This sensor is designed to measure fluid temperature e.g. oil, water or fuel. This signal may be used as a control value for engine control units or as a measurement value which is logged in a data acquisition system.
The NTC sensing element has a negative temperature coefficient. This means, that with increasing temperature the conductivity rises. The sensing element of 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 of a high quality production part and a robust and compact design.

Installation Notes
The NTC M12-H can be connected directly to most control units using a pull-up resistor (typically 1 or 3 kOhm). |
Any mounting orientation is possible. |
Please find further application hints in the offer drawing and free download of the sensor configuration file (*.sdf) for the Bosch Data Logging System at our homepage. |
Safety Note
The sensor is not intended to be used for safety related applications without appropriate measures for signal validation in the application system. |
