Abstract

Method and arrangement for measurement of rotational movement, in which a part 4 that forms a magnetic field and a part 19 placed in said magnetic field belongs to the arrangement that probes the rotation of the part being measured and part 19 has at least a first and second sensor 1 that measures the intensity of the magnetic field 3, in which said parts 4 and 19 rotate in relation to each other when the part being measured rotates. The data on magnetic field intensity that the first sensor transmits, is processed in the measurement unit as voltage data whose maximum value is recorded to mark a specific angular position in rotation, the data on magnetic field intensity that the second sensor transmits is processed in the measurement unit as amplifying voltage data, when the voltage data from the first sensor passes the maximum voltage point Ux and the amplifying voltage data from the second sensor is greater than Ux the measurement unit changes the voltage sign received from the first sensor 180 degrees around the voltage axis Ux to create an increasing voltage signal relative to a full revolution that occurs in the first direction. <IMAGE>
