  • Pneumatic weighing device
    Patent number: 6504113
    Abstract: The scales include a tray (1) placed on a base (3) and lifted by an air cushion, with no mechanical connection with the base (3). The weight of an object (21) laid on the tray (1) varies the air cushion pressure, and the measurement of this pressure by an external sensor (19) is straightforward and gives the weight of the object (21) once a law of correlation has been determined. Lateral pipes enable gas to be blown against a flange (2) of the tray (1) and thus horizontal displacements of the tray and friction to be avoided. Several vertical pipes are generally provided so as to reduce tray (1) tipping after the object (21) has been thrown off centre, the weight being then given by the sum of the measurements of each vertical pipe.
