A sensor device for measuring distance between a stator and a rotor in a machine is of the magnetic type and is intended to be mounted in the stator in order to interact with an opposing surface on the rotor. A sensor body ( 10 ) can be moved axially in a housing ( 11 ) mounted in the stator by means of an operating mechanism ( 13 ) and has a stop ( 16 ) at a predetermined distance (e) from its end surface designed to interact with a corresponding stop ( 17 ) inside the housing. This distance (e) exceeds the distance (d) between the stop ( 17 ) in the hosing and the end of the sensor body ( 10 ) by a predetermined distance (c) when the sensor body is in its normal measuring position. These stops ( 16, 17 ) make possible a particularly accurate calibration of the sensor device.
