  • Patent number: 6327913
    Abstract: The inventive force measuring cell consists of a plate (2) which is provided with a circular hole (2), the axis of which is perpendicular to the surface of said plate (2) and to the direction of the force that is to be measured. Said axis also lies within the neutral surface of the plate (2). The plate (2) can also be the web of a carrier. A measuring transducer (12) is inserted into the hole (3) in order to measure any modification of the size of the diameter of said hole (3) on a plane that is inclined at an angle of 45° counter to the direction of the force (F) to be measured. A lateral force is created in the direction of y in addition to a transverse stress &tgr; with a component &tgr;xy by applying force in the direction of y when at least one side of the plate (2) is clamped in the base. The originally circular hole (3) is deformed into an ellipse. The measuring transducer (12) consists of a measuring transformer with an oscillating string.

  • Patent number: 5834707
    Abstract: The bulk material, the amount o which is to be determined through second-integration or time-integration, passes over a top chute onto a bottom chute which is disposed at a tilt angle and defines the velocity of the bulk material. The bottom chute channels the bulk material to a slide which has the same angle of tilt as the bottom chute. The weight components of the amounts of bulk material on the slide acting orthogonally along the direction of the slide are determined by a load-sensing device. After passing down the slide the bulk material impacts a vertically arranged deflector plate which is rigidly connected to a connecting plate, with the deflector plate at that point generating a force through its change in its pulse action which is determined by a second load-sensing device. The second load-sensing device only measures the horizontal components of this change in pulse action, and, like the initial load-sensing device, is either parallel channelled or provided with parallel channelling.

  • Patent number: 5463192
    Abstract: A measurement instrument in which, when the initially loaded instrument is partly unloaded in such a fashion that the part load falls in a lower load range with a finer display-scale interval, the instrument continues to use the scale for the larger load until the load is removed completely. When the load is removed completely, however, the display reads "zero" as soon as the result R(m) at calculation stage m satisfies the condition .vertline.R(m).vertline..ltoreq.d.sub.jmax /2 (zero region) where d.sub.jmax is the largest display-scale interval. The next-finer display-scale interval is selected if the difference d.sub.s between two successive results determined at a particular time-interval satisfies the condition d.sub.j .ltoreq.d.sub.2 /10. A zero store is updated to include each result in the zero region.

  • Patent number: 5285860
    Abstract: The present invention concerns a process and a device for carrying out the process for weight determination of the contents of containers (5), for example for garbage. Two swivel arms (2) that are lifted by hydraulic devices (3) are mounted on a garbage collecting vehicle (1). The container (5) is carried by a fork (4). Integrated into the swivel arm (2) is a force measuring apparatus that comprises two flexural members (7) supporting the main load, two spring tongues (8), and a force transducer (11) that is installed between two stilts (12) between the spring tongues (8). The flexural members (7) and the spring tongues together form an elastic stepdown; the force transducer (11) thus only measures that part of the total load flowing through it as given by the stepdown. Further, a gradient meter (16) is mounted on the swivel arm (2), that has the same action line W as the force measurement device integrated in the swivel arm (2).

  • Patent number: 5050693
    Abstract: 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) measures 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 weighed independently 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 R.sub.1, R.sub.2 of the reference mass (8, 22, 24) at two different inclinations of the balance and the dynamometer (2) determines the weight (N.sub.1, N.sub.

  • Patent number: 4738325
    Abstract: A weight transducer including an extruded housing having upper and lower inner surfaces. Affixed to the upper inner surface is a hall effect magnetic field sensor, and affixed to the lower inner surface is a pair of magnetic field generating magnets. The magnets are arranged with magnetic poles of opposite polarity located adjacent one another. The hall effect sensor senses changes in the magnetic field generated by the pair of magnets due to relative movement between the upper and lower inner surfaces with application of weight to the housing. The voltage output of the hall effect sensor is converted to a signal having a frequency which varies in proportion to the weight applied to the housing. The hall effect weight transducer provides a very rugged and relatively inexpensive yet highly accurate weight transducer.
