ABSTRACT:
An electrical heating cartridge comprises a jacket, preferably of metal, at least one electrical heating coil and a thermocouple element positioned in the jacket which are imbedded with clearance from each other and from the jacket in a specially packed insulating material, wherein the electrical lead conductors of each of the electrical heating coils and the thermocouple element are guided out of a first end piece of the electrical heating cartridge. So that a rapid, controlled, uniform heating of the entire length of the cartridge is attainable, at least one electrical heating coil is directed toward a second end piece opposite to the first end piece of the cartridge and extended over and beyond the thermocouple element until adjacent the second end piece.
