The invention relates to a device for hot-dip coating a metal strand ( 1 ), especially a steel strip, in which the metal strand ( 1 ) is vertically guided through a container ( 3 ) accommodating the molten coating metal ( 2 ) and through a guide channel ( 4 ) disposed upstream thereof. The inventive device comprises at least two inductors ( 5 ) disposed at both sides of the metal strand ( 1 ) in the area of the guide channel ( 4 ) that are used to generate an electromagnetic field for retaining the coating metal ( 2 ) in the container ( 3 ), and at least one sensor ( 6, 6 ') for detecting the position (s) of the metal strand ( 1 ) in the area of the guide channel ( 4 ). In order to simplify and render more precise the detection of the position of the metal strand in the guide channel, the sensor for detecting the position of the metal strand ( 1 ) consists of two coils ( 6, 6 ') that are disposed, when seen from the direction of conveyance (R) of the metal strand ( 1 ), within the height (H<SUB>0</SUB>) of the inductors ( 5 ) between the inductors ( 5 ) and the metal strand ( 1 ). The invention further relates to a method for hot-dip coating a metal strand.
