With the development of sensor technology, electronic instrument, can output signals of the speed sensor and the weighing sensor corresponding mechanism, quickly replaced the mechanical belt scale and enlarge speed, weight, signal processing and implementation of operation can be done in electronic instrument weighing accuracy raised, scale frame structure is simplified, so the electronic belt scale rapidly fully replace the mechanical belt scale. But mechanical belt scales in the development process of about sixty years for the use of belt scales has accumulated a wealth of application experience, no mechanical belt scales yesterday, there is no electronic belt scales today.

Looking back over the past one hundred years, we can see that belt scales have been used more and more widely, and occupy a dominant position in all kinds of weighing instruments involving dynamic weighing systems. Looking into the future, the development of belt scales should focus on the following aspects:

The application of new speed sensors and weighing sensors with high accuracy and reliability;

Sensors such as tilt sensor, position sensor and other new detection content will be added to the application of belt scales;

Intelligent, bus-based and wireless transmission of secondary instrument;

The development and practical application of new verification methods for belt scales;

Deep research on the theory of belt scale weighing.
