摘要

A cone crusher shaft position measurement sensor arrangement (58) is arranged for measuring a position of a crushing shaft (30) of a cone crusher (1) of the type comprising an inner crushing shell (18), which is supported by a crushing head (16) mounted on the crushing shaft (30), and an outer crushing shell (12) which is supported on a crusher frame (2). The sensor arrangement (58) comprises a target means (62) adapted to be connected to the crushing shaft (30) and to move in a horizontal plane in concordance with the movement of the crushing shaft (30). The target means (62) comprises a sensor target (74). The sensor arrangement (58) further comprises at least one first sensor element (64) for sensing the horizontal position of the sensor target (74).
