Abstract
The invention relates to a device and a method for determining the vertical spacing of objects while carrying out positioning tasks with a vertical travel portion. The object of providing a device and a method for determining the vertical spacing of objects while carrying out positioning tasks with a vertical travel portion, which, or with which, respectively, a vertical spacing determination can easily be carried out even after a power failure with a low outlay for apparatus, is achieved by a device for vertical spacing determination in that at least a first pressure sensor (4) is arranged on a first object (1) and at least a second pressure sensor (5) is arranged on a second object (2) and evaluation means are provided, the objects (1, 2) changing their vertical position relative to one another while the positioning is being carried out and the vertical travel portion between the positions of the objects (1, 2) being determinable by the evaluation means from the difference of the measured pressure values of the first and second pressure sensor (4, 5).
