An apparatus for measuring the thickness of a slag layer on a metal melt in a metallurgical vessel comprises a first inductive eddy current sensor which indicates the distance of the apparatus from the metal melt as it is moved toward the melt. A second sensor detects when the apparatus reaches a predetermined distance relative to or contacts the slag layer and triggers the inductive eddy-current sensor when such distance is attained. The sensors are arranged in predetermined spatial relation and the thickness of the slag layer is determined by an evaluation device which analyzes the received signals. The apparatus permits measurement of the thickness of the slay layer without the need of additional equipment (e.g. mechanical lance movement or distance measurement).
