Patent number: 11965772Abstract: 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.Type: GrantFiled: January 23, 2019Date of Patent: April 23, 2024Assignees: Mettler Toledo Precision Instrument Company Limited, Mettler Toledo Measurement Technology Company Limited, Mettler-Toledo International Trading (Shanghai) Co., Ltd.Inventors: Haitao Zhang, Chunhui Li, Ping Zhang, Chenggang Ding, Tom Leahy

Patent number: 11029192Abstract: 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.Type: GrantFiled: September 9, 2019Date of Patent: June 8, 2021Assignees: Mettler-Toledo (Changzhou) Precision Instruments Co., Ltd., Mettler-Toledo (Changzhou) Measurement Technology Co., Ltd., Mettler-Toledo International Trading (Shanghai) Co., Ltd.Inventors: Rabin Shrestha, Tom Leahy, Ping Zhang, Ferenc Muranyi

Publication number: 20050081652Abstract: 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.Type: ApplicationFiled: October 21, 2003Publication date: April 21, 2005Inventors: Jon Scott, Tom Leahy, Philip Mariani
