Abstract
A device for producing at the output of a multivibrator an electric signal the period of which is a linear function of a temperature to which is subjected the measuring probe, characterized in that said multivibrator consists in a comparator whose first input comprises the probe, said probe consists in at least two semi-conducting junctions connected two by two in parallel and in opposite directions, and the other components of the device, particularly those of the second comparator input comprising a capacitor, remains invariable.
