摘要： Provided is a mass sensor including a four-corner-adjusting-mechanism capable of reducing the sensitivity of four-corner adjustment without reducing the rigidity of a Roberval mechanism. A mass sensor (1) includes a Roberval mechanism (2) in which a floating frame (21) and a fixing frame (22) are connected by upper and lower sub-frames (23, 24) having thin portions (23b) formed thereon, and a four-corner-adjusting-mechanism (4) to perform parallelism adjustment. The four-corner-adjusting-mechanism (4) includes an adjusting screw (41), and an upper elastic member (42u) and a lower elastic member (42d) disposed in series in the vertical direction so as to sandwich the sub-frame (23) to be subjected to parallelism adjustment.

摘要： The rod-shaped load cell consists of a guide section (1), which is subdivided into a frame (6) and a load-bearing element (7), and two parallel, rigid plates (8) connecting the two cited elements. Plates (8) are connected to both frame (6) and load-bearing element (7) by band-shaped flexural joints (9) which extend across the overall length of guide section (1). The load cell rests via frame (6) upon two feet (2) located outermost on rod-shaped guide section (1). The platform (5) rests upon two mounting elements (3) also located outermost on guide section (1), with the mounting elements (3) acting on load-bearing element (7). A force sensor (4) is diagonally installed at half the length of guide section (1). When platform (5) is loaded, tensile force acts upon force sensor (4) (see FIG. 1).

摘要： A load sensing assembly adapted to measure the weight of loads which act with both vertical and horizontal direction force components by resolving such force components solely into a vertical downward force component representative of the weight of the load is disclosed. This assembly comprises a first support member having a generally inclined leg portion fixedly mounted against movement, a second support member moveably mounted with respect to the first support member having a load support portion for supporting the load to be measured, a third member for interconnecting the first and second support members toward first ends thereof formed of elastically deformable material capable of transmitting only tensile force and no other types of force and a fourth member interconnecting the first and second support members toward the opposite ends thereof also formed of elastically deformable material capable of transmitting only tensile force and no other types of force. Together these four members form a quadrilateral load support structure for supporting a load to be measured which flexes under the load for transmitting only vertically downward forces applied by the load and no other forces. A load cell measures the load via the quadrilateral structure and produces a signal representative of the magnitude of the vertical downward force of the load.

摘要： A compact force transducer has at least one flexible beam mounted at one or both its ends to a force summing member or members. The force-to-be-measured is applied to the force summing member along a first axis generally transverse to the beams to deform the beam elastically, without overstressing, through a displacement d. A sensor member carries a conductive surface and is coupled to the beam member. In a parallelogram form, there are a parallel pair of beam members extending between two force summing members and a sensor member is secured to each beam member at or near its point of inflection. One sensor member includes multiple arms that sandwich the other sensor member to produce a linear, push-pull mode of operation. In a low cost cantilevered beam form, the sensor is coupled to the beam at the force summing member in a parallel, spaced relationship. In a hybrid push-pull form, the transducer uses a two beam parallelogram construction with cantilevered sensors (1) coupled rigidly to each beam adjacent one force summing member with a hinge coupling between the beam and this one force summing member, and (2) extending generally in a parallel spaced relationship with respect to an associated one of the beams.

摘要： The invention detects the weight of an object by detecting the change in electrostatic capacity due to a change in the distance between electrodes caused by deflection of flat plates, by using a pressure sensitive sensor having flat plates composed of two elastic insulators stuck together across a proper gap and extending parallel to one another, with electrodes provided at the confronting sides of the flat plates, and by transferring the load of the object to be measured to the sensor through a load support. The gap between the electrodes of this pressure sensitive sensor is enclosed, and a hole is provided to allow air to pass into and out of the gap. Furthermore, the surface of the pressure sensitive sensor is coated with a water-repellent substance to eliminate current loss due to dust or dew deposited on the surface of the electrodes. As a result, the weight may be measured accurately without being effected by temperature changes or humidity.

摘要： The weighing apparatus according to the invention is for use on a support surface which is subject to vibration. The apparatus includes a base adapted to be positioned on the support surface and having opposing first and second sides. The base is adapted to transmit vibrations from the support surface. A tray holds the product to be weighed and has a center of gravity adjacent the first side of the base. A load cell supports the tray on the base at the first side of the base. Strain gauges connected to the load cell generate a signal indicative of the weight of the tray and any product held thereby. The signal includes oscillating noise corresponding to vibrations transmitted by the base through the load cell to the tray. An auxiliary beam and counterbalance weight stablize the tray by minimizing at least some of the vibrations transmitted to the tray and by converting at least some of the lower frequency vibrations transmitted to the tray into vibrations having a frequency which is higher than the frequency of the lower frequency vibrations. The tray transmits reverse-phase vibrations to the load cell which result in noise in the signal. The auxiliary beam and counterbalance converts at least some of the reverse-phase vibrations transmitted to the load cell into vibrations having a frequency which is higher than the frequency of the reverse-phase vibrations.
