Abstract: A sensor device for contactlessly determining a revolution rate and a direction of rotation of a component that rotates during operation of the component, the component having, on at least one peripheral region, a circumferential structure of web-shaped or tooth-shaped radial protrusions and interposed grooves or tooth gaps includes: a threaded segment configured to positionally fix an arrangement of the sensor device so that the circumferential structure of the component is movable past the sensor device; a magnetic field generating device; and a magnetic field detecting device having at least three magnetic field sensors that are not arranged in alignment along a line. A distance between the magnetic field sensors that are the farthest apart from each other is less than or equal to a width of the grooves or tooth gaps of the component.

Abstract: The invention relates to a sealing gate (1) for strips for sealing a first chamber (2) in relation to a second chamber (3), a strip (4), in particular a metal strip, passing through both chambers (2, 3) and at least one sealing element (5) being provided for sealing the chambers (2, 3). The aim of the invention is to achieve an effective sealing action. To achieve this, the sealing element (5) has at least two gate elements (6, 7, 8, 9) that can be displaced in relation to one another and that have at least one sealing surface (10, 11, 12, 13), which is adapted to the edge contour of the strip (4) to be sealed.
