Abstract
There is provided a resistance element comprising a cylindrical carrier body, a rectangular bore therein in the direction of the longitudinal axis, a ceramic plate within said bore and securely bound to a flat wall of said carrier body, a thin layer platinum-resistor path with a temperature dependent electrical resistance firmly adhering to the surface of the ceramic plate opposite to that bound to said carrier body, electrical lead wires connected to said resistor path, said lead wires being secured to at least one end of said carrier body by an electrically nonconducting sealing composition and said lead wires passing through said sealing composition to the outside.
Claims2
A resistance element comprising a cylindrical carrier body, a generally rectangular bore therein, a ceramic plate within said bore having one surface secured to a flat wall of said carrier body, a thin layer platinum resistor path with a temperature dependent electrical resistance firmly adhered to the opposite surface of said ceramic plate, electrical lead wires connected to said resistance path, an electrically non-conducting sealing composition securing said lead wires to at least one end of said carrier body, said lead wires extending through said sealing composition to outside said carrier body.
