Abstract
A fluid sensor is provided for determining a fluid characteristic, having an electronic sensor element that has an active surface for determining the fluid characteristic, having a mounting plate associated with the sensor element, and having a filter device associated with the sensor element for filtering the fluid, in which the active surface of the sensor element is oriented toward the mounting plate and in which the mounting plate is provided with an opening opposite from the active surface of the sensor element. According to an embodiment the invention, an end region of the filter device is accommodated in a sealed fashion in the opening of the mounting plate. Furthermore, the fluid sensor can be used for tire pressure measurement.

A fluid sensor for determining a fluid characteristic, the fluid sensor comprising:
- an electronic sensor element that has an active surface for determining the fluid characteristic;
- a mounting plate associated with the sensor element;
- and
- a filter device associated with the sensor element for filtering a fluid, the filter device having an end region,
- wherein the active surface of the sensor element is oriented toward the mounting plate and the mounting plate is provided with an opening opposite from the active surface of the sensor element,
- wherein the filter device has an elastically compressible end region and the opening has a cross section that is smaller than the end region of the filter device, and
- wherein the filter device is accommodated in a sealed fashion in the opening of the mounting plate such that the end region of the filter device is elastically deformed in some regions by an elastic deformation that occurs in the joining process.
