A displacement measuring device measures a path of a moving object that can be displaced in a direction has at least one first component that is allocated to the moveable object and a second, stationary component. The components are interlinked for the purpose of converting a movement and/or displacement of the moving object into an electrical signal. The displacement measuring device also has an evaluating device for converting the electrical signal into movement and/or position information. The displacement measuring device has a high degree of accuracy, is not susceptible to wear, is resistant to vibration, shocks, or corrosion and is economical to use in almost all media. To this end, the first component is a spring element connecting the moving object and the second component is a force-measurement device which releases an electrical signal corresponding to the force that is exerted on the spring element.
A path-measuring device for measuring a path covered by a moving object deflectable along a direction with at least a first component associated with the moving object and a stationary second component, which are coupled with one another for converting a motion and/or deflection of the moving object into an electrical signal, and with an evaluating device for converting the electrical signal into motion and/or position information, wherein the first component is a spring element connecting a moving object and the second component, and the second component is a force-measuring device issuing an electrical signal corresponding to a force exerted on the spring element.
A method for determining at least one path covered by a moving object comprising:
A path-measuring device for measuring a distance traveled by a moving object, the path-measuring device comprising:
