Measurement method and device for the measurement of a path covered

摘要

With a measurement method and a measurement device for the measurement of a path covered by a first object ( 1 ) in relation to a second object ( 2 ), a measurement body ( 3 ) is deformed by a relative movement of the objects and at least a first deformation sensor ( 4 ) assigned to the measurement body ( 3 ) converts the measurement body ( 3 ) deformation into a measurement signal. The measurement signal is converted by an evaluation device ( 20 ) into information on the path covered. In order to increase the precision and measurement speed in a way that is simple structurally and saves space, the measurement signal is emitted when an area of the measurement body ( 3 ) is stretched along the longitudinal axis ( 6 ) of the measurement body ( 3 ) and a further area is compressed along the longitudinal axis ( 6 ) of the measurement body ( 3 ).
