Apparatus for measuring masses and forces
Реферат: 1320670 Measuring weight force electrically WIRTH GALLO & CO 27 March 1972 [ 2 Aug 1971] 14178/72 Headings G1N and G1W Apparatus for measuring weights or forces comprises two pre-tensioned electrically excited oscillating strings 2 each attached at one end to a movable central body 3, two motion transmitting members 6, 14 also attached at one end to the central body, the strings and members being so arranged that they radiate from the body in a star-like configuration, the member 6 transmitting a pre-tensioning force to the body and the member 14 transmitting a force which is a function of the mass or force to be measured, the apparatus further comprising a compensating lever 12 of which the effective length of the lever arm varies as a function of the weight or force to be measured, the force or mass 9 to be measured being transmitted to the member 14 through the compensating lever. The lever 12 comprises a rigid body 17 pivoted at 18 to the frame 1 and two V-shaped leaf springs 19 clamped at 21 to the body 17 in parallel planes, the springs being connected at their central parts 22 by a rigid rod 23 arranged parallel to the direction of action of the force to be measured. The effective length varies as the square of the applied force. The springs 19 are arranged to assume a horizontal position for a load equal to half of the range of loads which may be measured, when the effective length varies as the square of the difference between the mid-range load and the actual load.
