FIELD: measuring equipment.
SUBSTANCE: position indicator has constant magnet and Hall element. Constant magnet has through aperture, while aperture axis coincides with direction of magnet magnetization. Near aperture on one side of magnet Hall element is placed, and opening on the other side of magnet is positioned in area of movement of ferromagnetic element. Parameters of output signals ore adjusted by movement of Hall element relatively to aperture with alteration of working induction value in sensitive area.
EFFECT: maximal sensitivity with minimal size and mass of magnet.
