The force transfer system is the key component that determines the measuring performance of the weighing apparatus. Lever and deformation transmission systems are usually used.

The lever force transfer system is mainly composed of bearing lever, force transfer lever, support parts and connecting parts such as knife, knife bearing, hook, ring and so on. In FIG. 2, load-bearing levers 1 and 2 bear the load G from the load-bearing mechanism T, and the transfer lever 3 transfers the load from the load-bearing lever to the value indicating mechanism ─ the measuring lever 4.

In the deformation force transfer system, the spring is the earliest used deformation force transfer mechanism. Spring scales can weigh from 1 mg to tens of tons, and the springs used are quartz wire springs, flat coil springs, spiral springs and coil springs. Spring scale is greatly affected by geographical location, temperature and other factors, and the accuracy of measurement is low. In order to obtain higher accuracy, people have developed a variety of weighing sensors, such as resistance strain type, capacitance type, pressure magnetic type and vibrating string type, etc. The resistance strain type sensor is the most widely used.
