  • Temperature sensor for a resistance thermometer, in particular for use in the exhaust gas system of combustion engines
    Patent number: 7780348
    Abstract: The invention describes a temperature sensor for a resistance thermometer comprising an electric measuring resistor (3) the resistance material of which consists either of a ceramic material or of a metallic resistance material in combination with a ceramic or a mineral carrier, a protective tube (2) comprising a closed tip (2b) and a rear end that provides an access to the inner space of the protective tube (2) and that contains the measuring resistor (3) closely adjacent the closed tip (2b) of the protective tube (2), at least one supply line (5) that is brought out through the rear end of the protective tube (2), and an electrically insulating filler (6) based on a ceramic or a mineral material that fills the space between the protective tube (2) on the one side and the measuring resistor (3) and its at least one supply line (4, 5) on the other side. It is provided according to the invention that the packing density of the filler (6) has a gradient in lengthwise direction of the protective tube (2).
