Measuring device for measuring a distance
First Claim
1. A measurement arrangement (1) for the measurement of a diameter or a width of an object, characterized in that a first joint (2) is arranged at a first end (3) of an extended member (4), around which first end (3) the measurement arrangement (1) has a rotation axis (P), in that a second joint (5) is arranged at the opposing end (6) of the extended member (4), in that an equipment (11) for recording measured points is arranged at the second joint (5) and connected to it, in that the first joint (2) and the second joint (5) are connected through a cord (8) or a wire, in that the equipment (11) for recording measured points is arranged to be rotated through a pre-determined angle when the extended member (4) is turned around its rotation axis (P), in that an angle sensor is arranged at one of the joints in order to record a rotation of the equipment (11) for recording measured points relative to the extended member (4), in that the equipment (11) for recording measured points is arranged to be rotated by means of the cord (8) or wire through an angle that corresponds to the angle that the extended member (4) has been turned around its rotation axis (P), in that the equipment (11) for recording measured points and the extended member (4) are arranged to be rotated in opposite directions, in that the angles of rotation are recorded when the equipment (11) for recording measured points detects the limiting surface of the object on both sides of the diameter that is to be measured, and in that a processor is arranged to calculate the diameter based on the said angles of rotation.

Abstract
A measurement arrangement has a rotation axis around a first end of an extended member having a first joint thereat, and a second joint at the opposing end. An equipment for recording measured points is connected to the second joint. The joints are connected through a cord or wire. The equipment is arranged to rotate through a pre-determined angle when the member is turned around its rotation axis. An angle sensor records the rotation of the equipment relative to the member. The cord or wire rotates the equipment through an angle corresponding to the angle that the member has rotated around its rotation axis. The equipment and the member rotate in opposite directions, and the angles of rotation are recorded when the equipment detects the limiting surface of the object on both sides of the diameter to be measured. A processor calculates the diameter based on the angles of rotation.
