Abstract
A measuring device comprises a base, a case, and a rotating member rotatable about the axis of rotation. The rotating member comprises a transmission unit configured to emit transmission beams to different beam directions. The rotating member further comprises a receiver unit configured to receive returning transmission beams. A longitudinal member is fixed to the base and extends in a central area of the rotating member along the axis of rotation over a range including the transmission unit and the receiver unit. Two bearing members are arranged on the longitudinal member and on the rotating member. In the direction of the axis of rotation, the transmission unit and the receiver unit are located in a range between the two bearing members. The measuring device has a high aiming accuracy and low hysteresis of the turning transmission beams.
