Measurement method and device for the measurement of a path covered

Measurement method for the measurement of a path covered by a first object in relation to a second object, whereby a measurement body is deformed by the relative movement of the objects and at least one first deformation sensor assigned to the measurement body converts the measurement body deformation into a first measurement signal and then an evaluation device converts the first measurement signal at least into information on the path covered, comprising:

• the measurement body undergoes a deformation in which it is stretched in an area along a measurement body longitudinal axis and compressed in a further area along the measurement body longitudinal axis, whereby the first deformation sensor is stretched or compressed in one of the areas and a change in a physical property of the first deformation sensor caused by the stretching/compression is emitted as the first measurement signal;
• and
• at least a second deformation sensor arranged essentially spirally around the measurement body longitudinal axis in the opposite direction to the first deformation sensor emits a second measurement signal.

Measurement device for the measurement of a path covered by a first object in relation to a second object with at least one measurement body which can be deformed by the relative movement, to which at least a first deformation sensor is allocated to produce a measurement signal corresponding to the deformation, comprising:

• the deformed measurement body is stretched in an area along a measurement body longitudinal axis and is compressed in a further area along its measurement body longitudinal axis, whereby the first deformation sensor is essentially positioned along one of the areas;
• and
• wherein the first and second deformation sensors are connected at one end with each other and at their other ends in each case to a power source.
