Abstract: A gas-measuring probe for determining a physical characteristic of a measuring gas, in particular the concentration of a gas component or the temperature or pressure of the measuring gas, which includes a sensor element accommodated in a housing, at least one connection cable for the sensor element having an electrical conductor, which is enclosed by an insulation sheath and contacts the sensor element, and a cable channel sealing the housing end, which has at least one axial cable feedthrough through which the connection cable is guided out of the housing. To achieve long-lasting sealing at the cable-exit end of the housing even at higher temperatures, the insulation sheath of the connection cable is at least regionally welded to the cable wall of the cable feedthrough. To this end, a tube made of a material that fuses with the insulation sheath and the cable channel when heated is slipped over the cable section of the connection cable lying inside the cable channel.

Abstract: A gas sensor, whose purpose is to determine a physical property of a measuring gas, e.g., to determine the concentration of a gas component or the temperature of an exhaust gas. The gas sensor includes a sensor element arranged in a metal housing which is sealed by at least one sealing element arranged in a metal receptacle. The metal receptacle is affixed to the housing. The sealing element surrounds the sensor element in a centered position along its longitudinal extension L or on its half facing the measuring gas.

Abstract: A sensor for measuring a physical property of a measuring gas, in particular the oxygen concentration or the temperature in the exhaust gas of an internal combustion engine in a motor vehicle, has a housing, a measuring element whose end section protrudes from the housing, a connector plug mounted on the end section, and a housing shell covering the end section and connector plug with a radial clearance, one shell end of the housing shell being attached to the housing and the other shell end being sealed. To prevent electromechanical breakage in the sensor in the event of extreme vibration stresses or accelerations of the vehicle, the free space within the housing shell is completely filled with a non-conductive granulate.

Abstract: A detecting element is described, in particular a gas sensor for detecting the concentration of a gas component in a measuring gas, including a sensor element which is exposable to the measuring gas and has a connecting end section which is contacted by connecting cables and is exposed to a reference gas atmosphere. The end section is accommodated in a protective sleeve having a radial opening over which a gas-permeable diaphragm covering the at least one radial opening is provided, the diaphragm, in turn, being engaged by a clamping sleeve having at least one radial opening. To avoid the axial penetration of liquids between the clamping sleeve and the diaphragm, which would cause the detecting element to malfunction, the clamping sleeve is caulked axially above and below the radial openings. Both caulking zones are designed in such a way that the diaphragm is compressed with increasing force from the inner caulking edges facing each other to the outer caulking edges facing away from each other.

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.

The seal has a sealing element, which is fixed in position in a longitudinal bore of a metallic housing. The sealing element contains a mixture of steatite and at least one low-melting-point glass. To manufacture the seal, a prefabricated sealing ring made of a mixture of steatite powder and powdered glass is used, which is pressed in the longitudinal bore, the sealing ring being subjected to a thermal treatment, in which the glass is melted.
