Title:
A MEASURING DEVICE FOR MEASURING LARGE MASS WITH OPTICAL REFRACTION AND DISPLACEMENT MEASURING
Document Type and Number:
WIPO Patent Application WO/2018/040136
Kind Code:
A1
Abstract:
A measuring device for measuring the mass of a weight, comprising: a main frame (100); a main beam (200) supported on main frame (100); a balancing system (300) loaded on one end of the main beam (200); a weighting system (400), loaded on the other end of the main beam (200); a weight transportation system (500) capable of transporting and loading a standard weight (503) or a test weight (504) into the weighting system (400) and capable of unloading and transporting them away from the weighting system (400); and a control system (600) comprising an optical sensor (601) mounted in the main frame (100), a laser displacement sensor (602) mounted on the main beam (200), a monitor (604), and a control unit (603) connected electrically to the optical sensor (601), the laser displacement sensor (602) and the monitor (604). The control system (600) is adapted to compare a main beam (200) first displacement data obtained by the optical sensor (601) and a main beam (200) second displacement data obtained by the laser displacement sensor (602) to accurately measure the actual displacement of the main beam (200).
