Abstract
A cone crusher includes an outer crushing shell and an inner crushing shell forming a crushing gap there between. The outer crushing shell is supported on an upper frame member in vertically adjustable engagement with a lower frame member. A sensor arrangement having a sensor element is provided for measuring the vertical position of the outer crushing shell. The cone crusher further includes a target means arranged to be detectable by the sensor element, wherein one of the target means and the sensor element are arranged to follow vertical movement of the upper frame member and to move in relation to the other one of the target means and the sensor element. The sensor element includes a vertical sensing array which extends in a vertical direction along at least a portion of a range within which the target means may be moved upon adjusting the vertical position of the upper frame member.
