Abstract
The invention concerns a measurement sensor for the detection of temperatures in metal or alloy melts. This measurement sensor consists of a thermocouple (41) surrounded by a ceramic capillary (24) which is closed at its end by means of an adhesive (45) or the like. This measurement sensor is directly, i.e. without further sheathing, introduced into the melt (FIG. 3a).
