ABSTRACT:
A sensor for determining a physical property such as the concentration of a gas component or the temperature of a measuring gas, e.g., the exhaust gas of internal combustion engines, has a sensor element which is secured in a housing and is surrounded at an end section on the measuring gas side by a protective tube and surrounded at an end section on the connection side by a protective sleeve, and also has a radially projecting flange for securing the sensor on a sealing seat formed on a measuring gas duct. To reduce manufacturing costs, the flange is molded onto the protective tube as one piece. The protective tube is manufactured as a deep-drawn part, and a trimming edge remaining after deep drawing on the end side is used as a securing flange.
