摘要： A weight measuring apparatus can ensure safety even if a trouble or deterioration of measurement accuracy occurs. The weight measuring apparatus (10) measures a weight of fluids and includes the followings. A first arm (110) has a first fitting (111) to fit a supply fluid container (20). A second arm (120) is connected to the first arm (110) and has a second fitting (121) to fit a filtrate container (30). A third arm (130) is connected to the second arm (120). A first measuring device (220) measures, as a first total weight, a total weight of the supply fluid container (20) and the filtrate container (30) based on a change of the second arm (120). A second measuring device (230) measures, as a second total weight, the total weight based on a change of the third arm (130). An alarm (300) alarms, when the first and second total weights have different values having a difference equal to or greater than a predetermined value.

摘要： A load-sensing element is formed from a block of substantially rectangular cross section which is braced on a first end and which is adapted to receive a load to be measured on a second end. The block is pierced by an opening which is shaped such that at least two joints are created on each of a top side of the block and an underside of the block. The two joints on one of the top side and lower side of the block are offset from one another so as to compensate for a force eccentricity which occurs upon non-central introduction of the load to be measured. And a single strain gauge is disposed on the block in a vicinity of one of the offset joints.

摘要： A scale for measuring total weight/top weight of a bowling ball includes the utilization of a pair of electronic load cells supporting a moment transfer plate with the load cells being connected to a meter. In one form of the invention, the ball is centered over the load cells with its heavy spot in predetermined alignment so as to affect one load cell differently than the other. The ball is weighed simultaneously by both load cells, the total weight is determined by adding the outputs and the difference in output is used by the meter to calculate the top weight which is displayed. In another form of the invention, both a top weight and a total weight load cell are provided and the meter calculates the top weight directly from the top weight load scale.

摘要： A load cell device includes a load cell structure formed of a suitable metal and including vertically spaced apart, generally parallel horizontal elements integrally formed with longitudinally spaced apart, generally parallel vertical elements. Flexures interconnect each horizontal element with the vertical elements. A bending beam extends between and is interconnected with the horizontal or vertical elements. When a load is applied vertically and perpendicularly to one of the horizontal elements, the load cell structure will elastically deform as a parallelogram to thereby transfer shear force to the bending beam to cause shear-induced bending of the latter. Strain gages or frequency resonator crystal elements sense the shear-induced bending and are embodied in electronic circuitry which produces an output signal caused by deformation of the bending beam. The electronic circuitry is operable to convert the output signal to a perceptive force readout.
