摘要： A weighing device has not only a scale cell which weighs an object and outputs a weight signal indicative of the measured weight value but also a vibration-detecting load cell for detecting the vibrations of the floor to which the scale cell is set such that the effects of the floor vibrations can be subtracted from the weight value detected by the scale cell. The vibration-detecting load cell has attenuation-adjusting members adhesively attached to strain-generating parts of its load-sensitive element such that the attenuation constant of the load cell is thereby increased at least by a factor of 2. The usable dynamic range of the load cell can thus be increased while the load cell is kept compact. Butyl rubber members can be used for this purpose.

摘要： A damping mechanism is disclosed for use with a displacement measuring device, such as a load cell of the type immersed in a motion damping liquid contained within a housing. The mechanism includes a shear plate adjustably supported by the housing within the damping liquid for movement towards and away from a facing surface of the load cell, which is supported for movement within a plane disposed parallel to the shear plate, for purposes of controlling the thickness of the layer of damping liquid disposed there-between. The thickness of the layer determines the damping characteristics of the mechanism.

摘要： A hydraulic damper for an apparatus for measuring weight or force. The apparatus includes a base frame and an elastic load cell attached to the base frame, the elastic load cell having a movable part which vibrates relative to the base frame. The damper comprises pair of spaced support members fixed ot each other and to one of the base frame and movable part, a partition member fixed to the other of the base frame and movable part and positioned between the support members, a pair of flexible wall members extending between the partition member and the support members to form a pair of sealed chambers on opposite sides of the partition member, a narrow passage interconnecting the chambers, and liquid contained in the chambers whereby movement of the movable part of the load cell effects relative movement between the partition member and the support members to force liquid to flow between the chambers via the narrow passage thereby to damp the movement of the movable part of the load cell.

摘要： A scale has a load receiving member and a force receiving member coupled to the load receiving member by flat springs. The force receiving member transmits the force to be measured to a measuring cell. A hydraulic damper is connected in the force transmission path between the load receiver and the force receiver rather than between the force receiver and the frame of the scale as is current practice. The effects of viscous friction in the damper on the accuracy of the scale are thereby eliminated. The container holding the hydraulic fluid of the damper is sealed by a simple packing ring. Overload protection for the measuring cell is provided by a preloaded spring which is connected in series with the damper in the force transmission path.
