Abstract

The invention relates to an apparatus (10) for deternnining the surface profiles in particular the cathode wear profile (22) or the side ledge(s) profile of an aluminium electrolysis cell which is filled with an aluminium melt (5) and has side ledge(s) (6a) comprising a position determining system with a mobile system member (11) and a stationary system member (14) and a lance (16) with a heat resistant lance tip (19) for immersing into the melt (5) onto cathode or the side ledge(s) surface of the cell the mobile member (11) being attached to the lance (16) and the stationary member (14) being adapted for determining a position of the lance tip (19) by determining a position of the mobile member (11). Furthermore the invention relates to a method for determining the surface profiles in particular the cathode wear profile (22) or the side ledge(s) profile in an aluminium electrolysis cell by employing said apparatus (10) immersing the lance tip (19) of the apparatus (1) into the aluminium melt (5) onto cathode or side ledge surface (6a) of the cell and determining the position of the lance tip (19) as the height of the cathode (1) or of the side ledge (6a) at this position in the cell.
