A position and/or movement sensor for measuring a position or movement of a first object relative to a second object comprises a measuring device including a first member coupled to the first object; a second member coupled to the second object; and one or more first spring elements coupled between the first and second members; one or more stop members for limiting movement of the first member relative to the second member in at least one linear direction and/or about at least one pivot axis; and one or more second spring elements coupled between the first member and the first object. A spring constant of the second spring elements is greater than a spring constant of the first spring elements in at least one linear direction or about at least one pivot axis.
A measuring apparatus for measuring of positions or movements of two objects relative to one another with a force and/or moment sensor and a conversion spring element, with the force and/or moment sensor being elastically connected with one of the objects at least via the conversion spring element. A force and/or moment sensor with the measuring apparatus. A joystick with the measuring apparatus or the force and/or moment sensor.
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).
