摘要： A balance, which is virtually insensitive to angular deviation and to the presence of additional accelerations of the base, has two dynamometers (2, 3) each having a parallel guide (26). The parallel guides are mutually parallel and their degree of freedom coincides with the direction of gravitational acceleration when the balance is horizontal. The dynamometer (2) messures the weight (M) of the object to be weighed, and the dynamometer (3) measures that of a reference mass (8, 22, 24). The balance also has a computer (4) which, from the signals emitted by the two dynamometers (2, 3), accurately determines the mass of the object to be weighedindependently of the angular deviation of the instantaneous total acceleration. During calibration, which can be carried out only by the manufacturer, the dynamometer (3) determines the weight (R1, R2) of the reference mass (8, 22, 24) at two different inclinations of the balance, and the dynamometer (2) determines the weight (N1, N2) of the empty balance pan (18) and the total weight (M1, M2) using a known standard mass. After appropriate processing, the above-mentioned values and the parameters (s, S1, P, Q, R1, N1) derived therefrom are stored in the read-only memory (30) of the computer (4). The true mass is then determined from the instantaneous values of the weights (M, R) and the stored quantites.
摘要翻译：实际上对角度偏差不敏感的平衡和基座的额外加速度的存在，具有两个测力计（2,3），每个具有平行导轨（26）。平行导轨相互平行，当平衡水平时，其自由度与重力加速度方向一致。测力计（2）测量被测量物体的重量（M），测功机（3）测量参考质量（8,22,24）的重量。天平还有一台计算机（4），根据两台测力计（2,3）发出的信号，可以根据瞬时总加速度的角度偏差精确地确定待测物体的质量。在校准期间，只能由制造商进行校准，测力计（3）确定在天平的两个不同倾角处的参考质量（8,22,24）的重量（R1，R2），测功机（2））使用已知的标准质量确定空余量盘（18）的重量（N1，N2）和总重量（M1，M2）。在适当的处理之后，将上述值和从其导出的参数（s，S1，P，Q，R1，N1）存储在计算机（4）的只读存储器（30）中。然后从权重（M，R）和存储的量子的瞬时值确定真实质量。

摘要： The invention is a load cell for the measurement of force, independent of displacement, created by means such as weight, acceleration, pressure, and the like. The load cell has a beam structure with beams positioned parallel to each other in at least one plane. Generally, these parallel beams are attached to a stationary substrate and have sensing means attached between the two beams. In operation, deflection of one beam creates a response in the sensing means due to the relative action or deflection in the second beam.

摘要： The weighing device has a bending beam (20, 31, 41) from which bending moment transmission means (35, 36, 42, 43) extend laterally. Relatively rigid members (24, 27, 30, 32) are coupled to the bending moment transmission means (35, 36, 42, 43) by force transmission elements (13, 37, 38). Loads applied to the rigid members (24, 27, 30, 32) are measured by a strain gauge (33) mounted on the bending beam (20, 31, 41). Each force transmission element (13, 37, 38) comprises a rectangular prismatic body of elastomeric material, such as natural rubber, which may have concave sides (15) to reduce shear forces in the body. Fixing studs (17) may be attached to plates (16) bonded to the upper and lower surfaces of the body. The material of the body is chosen to exhibit creep, hystersis and linearity characteristics approximating those of an ideal spring.
