Sensor determining movement of electrically conductive thread - travelling in straight line between magnetic poles and coil for generation of dependent voltage

摘要

The sensar ascertains the movement of a thread of electrically conductive material as long as it at least approaches movement in a straight line. A magnet is installed across the space through which the thread moves. A receptor coil is placed before or behind the magnet to generate a voltage dependent upon the threads movement. The thread of regular conductivity can be wound with others to form a string or rope as used in suspended ropeways. Such a rope (1) can be brought to travel through an air column between two pole shoes (2,2'). These shoes have grooves (4) in which the coil windings (5,6,7,5',6',7') are embedded.
