Abstract
A gas sensor for determining a physical characteristic of a measurement gas, in particular its temperature or the concentration of a gas component in a gas mixture, having a sensor element that has end segments at the side of the measurement gas and at the side of the connection, a sheath that surrounds the sensor element with a radial distance and that has a protective tube, a housing, and a holding cap, and a sealing element that seals the sensor element against the sheath and that is situated on the sensor element between the measurement gas-side end segment and the connection-side end segment of the sensor element. In order to achieve a gas measurement sensor that can be manufactured economically and that has a reduced axial constructive height, and that provides a sufficiently good sealing against the measurement gas, the protective tube is provided at its end facing the sealing element with a tube base that has a central through-opening for the sensor element and that immediately abuts the sealing element, and that presses the sealing element axially between the cap base and the tube base.
