Verfahren zum Betreiben eines Widerstandsheizelementes und Vorrichtung zum Durchführen des Verfahrens

摘要

Disclosed are an operating procedure related to a resistance heating element (10) and the device for applying same. In a first step, the resistance Rh (11) of the heating element concerned (10) is determined at a given base temperature. In the second step, a set resistance value (12) is determined as compared with the resistance Rh (11) for a given base temperature and temperature coefficients which are also known. The resistance heating element (10) is actuated by setting an approximate resistance value (12) so that said element operates at the set value.
