Abstract
A measuring instrument for contactless detection of a path c is comprised of a two-part (14, 15) base plate (11), a side plate (16), and a movable part (12). The movable part (12) has a support plate (25) which is guided through a slot (26) in the side plate (16). At one end (27) of the support plate (25), there is a permanent magnet (28) which is embodied as smaller than the path (c). The magnet (28) can be embodied in one piece or in several pieces. Through the disposition of the magnet (28), it is possible to produce different sections, e.g. plateaus or sections deviating form the linear measurement line, in the measurement curve detected by the measuring instrument.
Claims7
A path measuring instrument, comprising at least two flux conducting parts composed of a magnetically conducting material;
- a movable magnet;
- at least one magnetic field-sensitive element located in a gap between said two flux conducting parts;
- a support plate on which said magnet is located, said support plate being composed of a magnetically conductive material so that said support plate is a component over which a magnetic flux runs, said magnet being formed smaller than a total measurement path.
