Abstract
measuring sensor, in particular for determining the oxygen content in the exhaust gases of internal combustion engines, includes a sensor element which is axially arranged in a metallic housing and which is contacted by at least one connecting cable, which is brought axially out of the housing, through a support sleeve member, and which has a cable insulation, a reference atmosphere for the sensor element being introducible into the housing, and the cable insulation, at the surface area, having, at least in certain regions, at least one gas-permeable section, such that the reference atmosphere arrives inside the cable insulation and, from there, in the housing. The gas-permeable region of the cable insulation is directly contiguous to the cable-output end of the support-sleeve member and sheathed there by a porous tube of gas-permeable PTFE material, while allowing for a radial clearance between the porous PTFE tube and the gas-permeable section of the cable insulation.
