Abstract
An installation includes at least one magnetic field source, measuring equipment fixed onto a freely movable object whose motion is to be detected, and control equipment. The measuring equipment includes a magnetometer able to measure the magnetic field it is surrounded by, a comparator able to test the magnetic field value against a threshold value, and a transmitter for transmitting a signal representing the result of this test. The control equipment receives this signal and derives therefrom the object displacement and/or its proximity to the source.
