Beschreibung
Zusammenfassung:	A field device includes a housing that contains field device circuitry, a display coupled to the field device circuitry and viewable through the housing, and a movable control positioned around the housing, the movable control including a magnet. The field device further includes a sensing element disposed within the housing and configured to detect movement of the magnet. In addition, the field device includes a processor coupled to the display and the sensing element. The processor is configured to identify a position of the movable control, based on the detected movement of the magnet, and control a user interface on the display, based on the identified position of the movable control.
