ABSTRACT:
A measurement sensor for determining a physical property of a measurement gas, e.g., the concentration of a gas component or the temperature of a measurement gas, in particular of the exhaust gas of internal combustion engines, has a housing and a sensor element accommodated in the housing. The sensor element has an end segment at the measurement gas side that protrudes from the housing and a connection-side end segment that bears at least one contact surface. The sensor element also has at least one conductor element that contacts the at least one contact surface. In order to achieve low transition resistances at the electrical contacting and a decoupling from mechanical stress, the contact surface and the conductor element are connected to one another by welding, and are embedded in a ceramic compound at least in the area of the welded connection.
