The electronic truck scale is a measuring tool. The structure of the electronic truck scale is composed of sensors, electronic weighing instruments and scales. The truck scale is also following the development of the times, from the mechanical electronic scale to the electronic truck scale, and the structure of the truck scale has evolved from the girder type and the channel steel type to the type with levers and sensors under the U-beam cover. What are the main structures of the electronic truck scale? The following manufacturers introduce to you:
1. Load cell
At present, the electronic vehicle weighing apparatus adopts the load cell, especially the resistance strain type load cell. It is a widely used sensor with high accuracy, good stability, mature technology and simple fabrication. A certain number of cantilever beam type or double cantilever bridge type load cells are used for the load cells of the electronic automobile scale according to the size of the scale and the length of the table.
In order to overcome the differences in output impedance and sensitivity of load cells, load cells are connected in full parallel, and adjustable resistors are installed in parallel at the output end of each load cell, so as to ensure the accuracy and reliability of weighing results.
2. Measurement display system
The measurement and display system of the electronic truck scale is to amplify the output signal of the front weighing sensor, and then display the mass value of the weighed item on the electronic truck scale in digital form through the A/D converter, microprocessor and display.
Weighing platform: weighing platform is generally made of metal materials, which can be divided into one, two, three and four stages, with high strength, high hardness and large use area.
Scale bridge and connecting parts: as an important framework of the table, the scale bridge plays an irreplaceable role. The quality of the scale bridge will affect the quality of the electronic truck scale.
The electronic automobile scale can be equipped with a variety of weighing display instruments according to the needs of users to achieve different weighing management and counting functions. For the chemical industry, the stainless steel workbench is equipped with explosion-proof electrical equipment, which can be used in anti-corrosion, waterproof and explosion-proof environment. Printer and large screen display can be selected, and corresponding functions can be expanded.
