Abstract
The invention relates to a sensor unit for measuring a measurable variable, especially in an aggressive medium. Said sensor unit comprises a sensor which is disposed in a sensor casing and is provided with a sensor zone located on a base. In order to detect the measurable variable in the sensor zone, a measuring hole which allows the medium to advance directly to the sensor zone is provided in the sensor casing. A side of the sensor zone that faces away from the measuring hole is equipped with a measuring surface which encompasses measuring electronics. An electrical feeder is provided on the sensor in order to transmit a sensor signal generated by the measuring electronics. The sensor is sealingly arranged on a sealing surface located on the sensor casing in such a way that the measuring surface is isolated from the medium. A mechanism is provided by means of a which the sensor can be disconnected from thermally and/or mechanically induced changes in the sensor casing. There also is a probe comprising a sensor unit, as well as an internal combustion engine, a hydraulic or pneumatic tool, and an air conditioner encompassing a sensor unit.
