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.
