The future trends of belt scale:With the development of sensor technology and electronic instrumentation technology,speed sensor and weighing sensor which can be output electrical signals quickly replaces the corresponding mechanical belt scale,while to enlargement processing the speed,weight signal and operations can be done on electronic instruments,weighing accuracy improves,scale aircraft structure is simplified,so belt scales replace the mechanical belt scales rapidly and comprehensively.

Belt scale mainly consists of four parts:weighing sensor,speed sensor,scale aircraft,the display controller,scale aircraft is carrying the materials on the belt pass perpendicularly to the load carrying and transmitting devices of weighing sensor according to a specific proportion,it is the first link of the process of weighing materials. Although it seems simple,it is an important foundation part of the belt scale,the design strength,rational use of the material,machining precision,directly determine the level of the entire device,and is essential for the stability of the measurement process.

Review a hundred years of history that has gone through,we see that the applications of belt scale have been increasingly widespread,and dominant in all kinds of scales involving dynamic weighing system.Looking to the future,the development of the belt scale should focus on the following aspects:

*High accuracy and high reliability of the applications of the new speed sensor and weighing sensor;

*Tilt sensor similar to the new test content,position sensors and other sensors will be added to the applications of the belt scale;

*Secondary instrument intelligent,bus,wireless transmission technology;

*In-depth study of the weighing theory of belt scale.
