Measuring system

A measuring system:

• a magnetic field sensor array;
• an evaluation circuit for evaluating measurement signals of the magnetic field sensor array;
• and
• an encoder having a linear guide and a mass element to change a magnetic field vector in the magnetic field sensor array, the encoder having a spring element, the mass element being attached to the spring element, the mass element being adapted to be guided in a radial direction in the linear guide such that during a rotation of the encoder the mass element is moved by centrifugal force and the centrifugal force works against the spring force of the spring element, and
• wherein the magnetic field sensor array is arranged toward the encoder to measure a change, caused by the movement of the mass element, in the magnetic field vector, and
• wherein the magnetic field sensor array has a magnet and/or a coil for magnetic field generation, and
• wherein the magnetic field sensor array has at least one magnetic field sensor, and
• wherein the magnetic field sensor is arranged between the encoder and the magnet and/or coil.
