Abstract
PURPOSE: To permit the field-type sensor to detect the passing direction of an object without malfunction by arranging a plurality of sensing wires on both sides of an exciting wire to detect the difference between the induced voltages of the sensing wires or the ratio of one induced voltage to the other.
CONSTITUTION: When the object M to be sensed passes in the direction of from the sensing wire 3a to the sensing wire 3b, at a position (b) a difference voltage VA-VB between the induced voltages of the sensing wires 3a and 3b is produced. At a position (c) no difference voltage is produced, but at a position (d) a difference voltage is produced. When the object M moves in the direction of from (a) to (e), VA-VB changes from negative to positive. On the other hand, when the object M moves in the direction of from (e) to (a), VA-VB changes from positive to negative. In addition, when the output of a level slicing circuit 5 changes from negative to positive as the object M moves, the output of an AND circuit 14b is obtained as a direction sensing output; when the output of the circuit 5 changes from positive to negative, a different direction-sensing output is obtained. By this, the crossing direction of the object M can be distinguished. The constitution, in which the induced voltage difference and the like are detected and passed through the level slicing circuit, permits the detection of the passing direction of the object without malfunction.
