Abstract
A method for measuring a length variation of a spring, comprising the steps of associating a measurement device with a spring, determining a measurement of the intensity of a magnetic field of the measurement device, and, on the basis of the measurement of the intensity of the magnetic field, determining the length variation of the spring.

A method for measuring a length variation of a spring, comprising the steps of:
- providing a measurement device that comprises;
- at least one magnet for generating a magnetic field;
- at least one magnetic field sensor;
- and a supporting element to which said at least one magnet and said at least one magnetic field sensor are fixed;
- connecting said measurement device with a spring such that said measurement device is fixed to said spring at a single point;
- generating, by means of said at least one magnet, a magnetic field such that said magnetic field pass through turns of said spring;
- determining the intensity of said magnetic field of said at least one magnet of said measurement device;
- on the basis of said measurement of the intensity of the magnetic field, determining the length variation of said spring.
A spring comprising a measurement device which is adapted to allow detection of the variation of a length of said spring with respect to an inactive condition, wherein said measurement device comprises at least one magnet, at least one magnetic field sensor, and a supporting element to which said at least one magnet and said at least one magnetic field sensor are fixed, said measurement device being fixedly connected to said spring at a single point such that said at least one magnet generates a magnetic field that passes through turns of said spring and through said magnetic field sensor that detects an intensity of said magnetic field whereby said intensity depending on the length variation of said spring.
