Abstract

A sensor sheath for a thermal air flow rate sensor that is intended for disposition in a pipeline through which a fluid flows. In order to prevent the spread of ignition to the remainder of the fluid upon ignition of the fluid in the surroundings of the sensor, a wire grid is provided with meshes which are embodied such that a fluid flows substantially unimpeded through the wire grid, and which has an opening through which the sensor to be sheathed can be introduced into the wire grid.
