[0002] Weighing equipment usually refers to the weight measuring equipment used for large objects in industry or trade. It refers to the use of modern electronic technologies such as program control, group control, teleprinting records, and screen display, which will make the weighing equipment fully functional and more efficient. Weighing equipment mainly consists of three parts: load-bearing system (such as scale pan, scale body), force transmission conversion system (such as lever force transmission system, sensor) and indication system (such as dial, electronic display instrument).
