A measuring arrangement in the form of a measuring counter, a measuring slide or a measuring screw. The measuring arrangement comprises a housing in which a measuring unit, a transmission circuit and a receiving circuit are arranged on a common conductor plate. The transmission circuit and the receiving circuit use a common conductor plate antenna which is also provided on the conductor plate. A voltage supply circuit for supplying a voltage to the measuring unit, the transmission circuit and the receiving circuit is also arranged on the conductor plate. Via a measurement value sensor at the housing a measurement value is detected and converted by the measuring unit into an electrical measurement signal and transmitted via the transmission circuit wirelessly to an external central unit.

Measuring arrangement with transmission circuit for wireless transmission of a measuring value

A distance measuring instrument has a measuring axis; a measuring spindle disposed rotatably and shiftably in a housing such that a rotary motion of the measuring spindle results in a corresponding shift of the measuring spindle along the measuring axis; a stationary sensor element which is immobile relative to the housing and a movable sensor element which is connected to the measuring spindle to rotate therewith and which is shiftable relative to the measuring spindle along the measuring axis; and a guiding device for guiding the relative shifting motion between the movable sensor element and the measuring spindle, and having a guiding sleeve connected to the movable sensor element for rotation therewith; the guiding sleeve has an inner groove which extends parallel to the measuring axis and a guiding member which is connected to the measuring spindle for rotation therewith and which projects shiftably into the inner groove.
