[0002] Electronic truck scales are a very common large-scale measuring equipment, widely used in the measurement and data management of incoming and outgoing materials in industries such as trade, transportation, warehousing, mining, factories, ports and terminals. Electronic truck scales use the principle of strain gauge electrical measurement to weigh. Strain gauges are attached to the elastic body of the weighing sensor to form a Wheatstone bridge. When there is no load, the bridge is in a balanced state and the output is zero. When the elastic body is under load, each strain gauge will produce a strain proportional to the load, and the external load can be measured by the output voltage. When the electronic truck scale is processed, a positioning device is required for fixation.
