ABSTRACT:
A process for measuring the temperature of a bath of molten metal comprises bringing a heat sensitive element into contact with the molten metal whereby the element, which comprises an electrically insulating material is, progressively destroyed by combustion when in contact with the bath. The duration of combustion of a predetermined length of this insulating material is measured, from which duration the temperature of the bath can be ascertained. The duration is timed by means of electrodes immersed within the insulating material, which electrodes terminate at different levels therein and are used to activate or deactivate a counter for counting the pulses of a clock arrangement.
