  • Patent number: 11965772
    Abstract: A calibration device is provided for a weighing system that has a tank with a plurality of support legs at a lower part thereof. The calibration device has at least one calibration module, a hydraulic system and a calibration terminal. An upper end of each calibration module is connected to an upper part of a corresponding support leg. A lower end of each calibration module is fixed to a foundation. A hose connects each calibration module to the hydraulic system for applying a force to the tank. The calibration terminal, connected to each calibration module, displays in real-time, the force applied to the tank. The calibration device can greatly improve the production efficiency, and in use, takes only two hours to complete the calibration, which is faster than the test weight and other calibration methods.

  • Patent number: 11029192
    Abstract: A high-capacity weighing module has a top plate weldment (10), a bottom plate weldment (30) and a pressure-bearing assembly (20) that is between the top and bottom plate weldments. Motion between the respective top and bottom plate weldments is restricted. This structure aids in easy installation and replacement of a sensor, and integrates the functions of anti-overturning and 360° inspection, and bottom stop. This makes the weighing module much more convenient to install than a conventional high-capacity module, and has a better safety function. The weighing module has advantage in terms of a simplified product structure, reduced cost of manufacture and maintenance, uncomplicated installation procedure, and higher safety and protection.

  • Patent number: 9612150
    Abstract: A weigh module (1) includes a load cell (2), a base plate (3), a top plate (6), a force-transmitting member (8) serving to transmit the weighing force from the top plate (6) to the load cell (2), and movement-restricting means (9, 10) which serve to limit the horizontal floating movement of the top plate (6) relative to the base plate (3) within a confined range of free play and to transmit lateral force components directly from the top plate (6) to the base plate (3). One part of the movement-restricting means (9, 10) has the form of a channel whose top edges (11) are rigidly connected to the top plate (6) and whose flat bottom extends parallel to the base plate (3) at a clear distance from the latter.

  • Patent number: 7371978
    Abstract: Weighing module having a first mounting device which is in force-transmitting contact with a load that is to be determined, also having a second mounting device which is connectable to a supporting structure that supports the weighing module. A load cell is arranged between the mounting devices and cooperates with a load-transmitting device. The weighing module has a first and a second receiving cup, each of which has a concavity designed to receive the force-transmitting element, which receiving cups are arranged between the mounting devices. At least one concavity has an elliptical cross-section in a plane that is substantially orthogonal to the direction of the load.

  • Publication number: 20050081652
    Abstract: A new load cell design that is a combination of the column cell and proving ring designs while having the best features of both. The proving ring geometry is used to boost the transverse gage output giving tension and compression strain measurements that are more equal than in a column cell, while the gage placement is the same as a typical column cell, giving a superior temperature transient behavior. The device retains the high stiffness characteristics of column cells.
