ABSTRACT:
A 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 are fixed to a force distributor. The force distributor is guided in a statically determined way relatively to the frame by means of the two strings, and by means of at least one guide with forming the first transmission element respect to the pre-loading force and to the force depending on the load to be measured, said guide being elastic and under a bending pre-tension and able to transmit moments, so that it generates the pre-load of the strings and transmits it to the force distributor.
