Abstract:
A temperature sensor comprising:a sensor tube; a sensor rod received in the sensor tube and having a thermal expansion coefficient which differs from a thermal expansion coefficient of the sensor tube, said sensor rod having one end, which is supported by a free end of the sensor tube, and another end, which forms an actuating element of a switching contact assembly; an insulating member constructed to at least partly surround the switching contact assembly and having an opening for passage of the sensor tube with accommodated sensor rod; a support plate mounted to the insulating member in the area of the opening and connected at least indirectly to the sensor tube by a welding process such that an opening-surrounding wall portion of the insulating member is held in place, and a tubular insert placed into the opening for support of the sensor tube, said support plate welded to the tubular insert so that the opening-surrounding wall portion of the insulating member is held between the support plate and the tubular insert.
