What is the main structure of electronic truck scale?

Electronic truck scale structure 1. The bearing (1) weighing platform Weighing platform is generally made of metal materials, with a section, two sections, three sections and four sections of the points. It has high strength and hardness, and has sufficient area of use. (2) scale bridge and connector Scale bridge as the frame of the table has an irreplaceable role, its quality will affect the quality of electronic truck scale. (3) limit device The horizontal limit device of electronic truck scale can eliminate other interference and ensure the weighing result is stable and reliable. And the electronic truck scale overload limit device, is to protect the electronic truck scale device, and then protect and prolong its service life, to prevent serious overload of electronic truck scale damage. 2. Weighing sensor At present, electronic truck scale adopts weighing sensor, especially resistance strain type weighing sensor. It is widely used as a sensor with high accuracy, good stability, mature technology and easy production. The weighing sensor of electronic truck scale adopts a certain number of cantilever beam type or double cantilever bridge type weighing sensor according to the scale size and the length of table. In order to overcome the differences in output impedance and sensitivity of multiple weighing sensors, the weighing sensors are connected in full parallel connection, and the adjustable precision resistance is installed in parallel connection at the output end of each weighing sensor accordingly, so as to ensure the accurate and reliable weighing results. 3. Measurement display system The measurement and display system of the electronic truck scale amplifies the output signal of the weighing sensor in front, and then through A/D converter, microprocessor and display, the mass value of the goods on the electronic truck scale is finally displayed in the form of numbers. Of course, electronic truck scale has other devices and printing devices and other components.
