Abstract

PURPOSE: To improve and stabilize detection precision by using multiple winding coil elements which are arranged and connected specially.
CONSTITUTION: The lstW3rd winding coil groups 6W8 composed of coil elements 6aW6d, 7aW7d, 8aW8d connected in parallel to one another are arranged on the travel course of a movable matter 1 composed of magnetic matters. Parallel bodies of the coil elements 6aW8a, 6bW8b, 6cW8c, 6dW8d and detecting resistors 9aW9d are connected in series and the 1stW3rd coil groups 6W8 are connected with comparators 10aW10c and reference voltage comparators 11aW11c of a group selection circuit 13. Thus, the current which flows in the detecting resistors 9aW9d changes according to positions of the movable matter 1 and that voltage is compared with the voltage from the reference voltage generating circuit 12 by means of the reference voltage comparator 11aW11c, a signal from one of the 1stW3rd coil groups 6W 8 which has caught the position of the front end of the movable matter 1 is input from the group selection circuit 13 to an operation circuit 14 and in which of the winding elements 6aW8d the movable matter 1 is positioned is displayed on an indicator 15.
