Loader electronic scale is a high-tech product that combines computer technology and sensor technology, and is widely used in mining, coal, railway stations, freight yards, factories and other fields. It can be installed and used on various loaders without changing the original structure of the loader.
Working principle of loader electronic scale: Measure the pressure difference between the two ends of the lifting pressure cylinder piston of the wheel loader, and use digital modeling software to convert the pressure difference into a weight signal; The weighing process is dynamic weighing, which involves weighing during the process of shoveling and continuously lifting materials. The position sensor controls the pressure sensor to collect the effective value of the signal, and the industrial bus computer performs data calculation and processing, editing, and printing; According to OIMLR51Y (b) regulations of the International Organization for Legal Metrology, the weighing error can be within 1%.
The electronic scale is equipped with a 240 × 128 graphic display screen and background light, suitable for night work or tunnel work, such as weighing underground loaders in coal mines. The display screen not only shows the weight and cumulative weight of the materials in the tipping bucket, but also displays information related to weighing, such as the name of the company that purchased the materials, the number of the truck or train, and the type of materials.  
The electronic scale displays real-time time and date, and can set the loading limit of the truck or trailer.
