The invention relates to a sensor arrangement for measuring parameters in melts, in particular for measuring the temperature, in particular in metal or cryolite melts having a melting point above 500°C, with an upper part and lower part releasably disposed on the upper part. The invention is characterised in that on an immersion end of the lower part facing away from the upper part a tube is disposed coaxially with respect to a longitudinal axis of the lower part, said tube being closed at the end thereof facing away from the upper part end and open at the other end. In the upper part a guide tube which extends coaxially with respect to a longitudinal axis of the upper part and is open on both sides is movably disposed in a guide sleeve, wherein a pressure acting in the direction of the lower part is applied to the guide tube by means of a resilient body and said guide tube bears against the lower part, and wherein an opening of the guide tube and the open end of the tube of the lower part are disposed adjacent to one another and coaxially with respect to the longitudinal axis of the lower part. |
