1. An electrical heating device comprising:

  • a. at least one support;

    b. at least one ohmic heating resistor; and

    c. at least one temperature sensor;

    wherein the at least one ohmic heating resistor comprises at least one heating conductor strand, the at least one heating conductor strand is laid out on, or in, the at least one support in a track-like, curving, or meandering pattern in order to span a heating field,wherein the at least one heating conductor strand comprises at least one measurement loop, which is formed by two straight heating conductor strand sections that are separated from one another and connected together electrically conductively at one end, the two straight heating conductor strand sections are laid out around the at least one temperature sensor and thereby form a delimited measurement field,wherein the at least one temperature sensor is placed in a measurement position within the delimited measurement field spanned by the at least one measurement loop in such a way that the at least one temperature sensor;

    i. has approximately a same distance from the two straight heating conductor strand sections of the at least one measurement loop, andii. is positioned within the at least one measurement loop as a function of a surface area formed by the delimited measurement field.
