Abstract
The disclosed embodiments describe force-transmitting devices for use in gravimetric measuring instruments. The force-transmitting devices scale the force from a calibration weight to facilitate calibration and weighing. The devices comprise unidirectional coupling elements. The unidirectional coupling element comprises coupling element parts. The elements may be adapted to transmit only a tensile force or only a compressive force to a measurement transducer. Adapting the unidirectional coupling element to transmit one type of force or the other may be done by selecting an appropriate arrangement of coupling element parts. The coupling element parts are adapted to transmit force along a midline axis by either a projection and v-shaped groove coupling or projections on the first part mated with surfaces on the second part adapted to receive and guide the first part.
