The electronic hanging scale consists of three components: a sensor, a scale frame, and a weighing display controller. The Yajin electronic scale frame is used to transmit the weight of items on the transmission belt to the weighing sensor for load reception and transmission installation. It is also the first conversion stage in the weighing process of items, as it is the most important component of the electronic transmission belt scale. The accuracy and stability of a certain link play a decisive role in the functionality of the electronic transmission belt scale. It is also important to avoid overloading the weighing sensor during use.
