Abstract
The invention comprises a method and arrangement for indicating angle or direction in which a position and direction of movement of an inclination-sensitive level 4, 8 or the like is observed with a system formed of capacitors and reported to the user by signal devices when the signals received from separate capacitors are in balance. The levels 4, 8 are positioned in the electric field of the capacitor system, which is formed of at least three capacitor plates 1, 2, 3 or 7, 11, 12, ... n) so that when the balance bubble 5, 10 is in the balance position, which shows the desired angle of direction, the signal fed to plates 1, 7 from at least two plates 2, 3 or 11, 12, ... n is essentially equivalent. <IMAGE>
