Abstract

An angle of rotation sensor for measuring the angular position of a rotary shaft during more than one revolution consists of a fine angle of rotation sensor linked to the rotary shaft and of a counter. The revolutions of the shaft are all counted without mechanical gears, without an outer voltage supply and without supply batteries, with a simple and economical design. Pulse wire movement sensors supply voltage pulses depending on the rotation of the shaft. The number of voltage pulses is stored in a non-volatile read/write memory.
