Abstract
Heating cartridge with a tubular metal sheathing, whose interior houses an electrical heating element that is wound on a winding form and is electrically insulated from the tubular metal sheathing by embedding in an electrically non-conductive insulating material, and at least one temperature sensor with supply lines, wherein at least one supply line, preferably both supply lines, of at least one temperature sensor runs between the winding form and the tubular metal sheathing and is electrically insulated from the winding form and the heating element wound thereon and also from the tubular metal sheathing.
Claims14
A heating cartridge comprising:
- a tubular metal sheathing having an interior
- an electrical heating element housed in the interior, the electrical heating element wound on a winding form and being electrically insulated from the tubular metal sheathing by embedding in an electrically non-conductive insulating material;
- and
- at least one temperature sensor with supply lines, wherein at least one of the supply lines runs between the winding form and the tubular metal sheathing and is electrically insulated from the winding form, the heating element, and the tubular metal sheathing, wherein the winding form and the at least one supply line are held in recesses of an insulating element.
A heating cartridge comprising:
- a tubular metal sheathing having an interior;
- an electrical heating element housed in the interior, the electrical heating element wound on a winding form and being electrically insulated from the tubular metal sheathing by embedding in an electrically non-conductive insulating material;
- at least one temperature sensor with supply lines, wherein at least one of the supply lines runs between the winding form and the tubular metal sheathing and is electrically insulated from the winding form, the heating element, and the tubular metal sheathing;
- and
- at least three connecting wires for contacting the supply lines and contacting the electrical heating element, wherein at least one of the at least three connecting wires runs at least in some sections through the winding form and wherein at least two of the at least three connecting wires run outside of the winding form.
