<p>Mass and force meter with a frame, a load-support and a measuring system, wherein the mass or force to be measured acts indirectly on the tension of two transversally vibrating, pre-loaded strings excited by electronic means, so that the resultant frequency changes serve for calculating the magnitude of said mass or force in a computing device, both strings, a first transmission element for the transmission of a pre-loading force and a second transmission element for the transmission of a force depending on the load to be measured being fixed to a force distributor guided in a statically determined way relatively to the frame by means of the two strings and of at least one guide with respect to the pre-loading force and to the force depending on the load to be measured. The force distributor comprises three parts forming a triangle, both strings, the guide and both transmission elements being fastened to the corners of the force distributor.</p> |
