Abstract
An electronic measuring tape that includes a roller onto which the measuring tape is arranged to be wound up onto and wound out from through the roller being rotated, a first end of the measuring tape is attached in the roller, and where the roller is located inside a housing. A rolled up measuring tape is arranged in loops on the roller. All loops are in direct contact with the surface of the roller, an angle sensor is arranged at the roller to record an angle of rotation during rotation of the roller. An electronic circuit converts the angle of rotation into a length that corresponds to the length by which the measuring tape has been withdrawn from the housing, and the measuring tape records absolute values.
