Device for monitoring action of electromagnetically operated valve has short circuit ring mounted at defined stroke length beneath Hall sensor switch and connected to evaluation unit

摘要

The device has a circular magnet (9) mounted on the armature (7) opposite a Hall sensor switch (4) in the yoke housing (11) so that the sensor is subjected to the magnetic field of the magnet. A short circuit ring (10) mounted at a defined stroke length beneath the Hall sensor switch is connected to an evaluation unit.
