Abstract
A measuring device for measuring the position of a first body to a second body comprises a scale band that can be attached to the first body and that comprises a marker, wherein the measuring device comprises two marker detection sensors that can be attached to the second body, wherein the marker is formed by a pattern out of marker stripes, which transitions between a first position of the scale band and a second position are respectively arranged predetermined inclined to the transversal direction of the scale band in such a respective inclination angle that each of the inclination angles has a value that differs from the values of the other inclination angles.

Measuring device (1) for measuring the position of a first body (2) to a second body (3) being neighboured to the first body (2) and being movable relative to the first body (2), wherein the measuring device (1) comprises a scale band (4) that can be attached to the first body (2) and that comprises a marker, wherein the measuring device (1) comprises two marker detection sensors (5, 6) that can be attached to the second body (3), wherein the marker is formed by a pattern out of marker stripes (7), which transitions (8) from marker stripe (7) to marker stripe (7) between a first position (9) of the scale band (4) and a second position (10) being arranged in the longitudinal direction of the scale band (4) in a distance to the first position (9) are respectively arranged predetermined inclined to the transversal direction (12) of the scale band (4) in such a respective inclination angle (13) that each of the inclination angles (13) has a value that differs from the values of the other inclination angles, wherein the scale band (4) is divided in transversal direction into two traces (17, 18), wherein one of the marker detection sensors (5) is arranged neighboured to the first trace (17) for detecting the inclination angle (13) on a position of one halve of one of the marker stripe transitions (8) and the other of the marker detection sensors (6) is arranged neighboured to the second trace (18) for detecting the inclination angle (13) of another position of one of the marker stripe transitions (8) as well as the marker detection sensors (5, 6) are arranged seen in the transversal direction (12) of the scale band (4) next to each other between the first position (9) and the second position (10), so that the position of the first body (2) to the second body (3) can be determined within the first and the second position (9, 10) by detecting the inclination angles (13).
