ABSTRACT:
A mass and force meter comprising a frame, a load support, a digital evaluation and display device and two electrically-excited, transversely-vibrating, pre-tensioned strings each having one end fixed to the frame. The other ends of the strings are connected to a force distributor, and first and second transmission elements are provided for transmitting to the force distributor a pre-tensioning force and a force which depends on the load to be measured. One end of each of the transmission elements is fixed to the force distributor and the other ends are connected to the respective pre-tensioning and load forces. A guide member having one end connected to the frame and the other end connected to the force distributor acts together with the strings to guide the force distributor in a statically defined manner relative to the frame with respect to the pre-tensioning force and the force established by the load to be measured. Means are further provided for applying to the evaluation display device the resultant frequency variations caused by application of load to the strings thereby permitting measurement and display of the magnitude of the measured load.
