ABSTRACT:
An accelerometer comprising a permanent magnet which, when idle, is maintained dynamically balanced by virtue of magnetic fields acting on opposite sides in relation to its poles, and which is designed to travel along a respective guide. The accelerometer has a coil arranged coaxially in relation to the traveling direction of the magnet, and is designed to generate an electric signal, the intensity of which depends on the relative acceleration of the coil in relation to the magnet and in the traveling direction of the same.
