<p>The instrument has a current carrying coil generating a magnetic field, and there is a small movable ferromagnetic plate (9) in the coil field. The ferromagnetic plate is mounted so that it can rotate about its axis in a direction opposite to the action of a spring, and is connected to a pointer. The small plate (9) is an S-shaped flat element. It is symmetrical to its axis of rotation (10) on which it is mounted, and it is designed to carry out angular movements caused by the magnetic field.</p> |
