Abstract
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.
