Device to control and measure temperature applicable to electric resistances, characterised essentially in that on the terminals of resistance 1 there is a voltage connection 3 and current reader in series with the same 4, the data from which arrive at a calibrating measuring circuit of the resistance 5 where the instantaneous value of the electric resistance is calculated corresponding to the cold resistance element, calibrated against the value of the ambient temperature. The values obtained from the measurer-calibrator 5 are applied in a regulator 6, to which is allocated a discharge of triacs or thyristors by phase control 8 on which depends the energy applied to the transformer 2 which feeds the resistance element.
