Under normal circumstances,0.5 accuracy of belt scale is used for trade settlement,1.0 of belt scale is used for internal accounting,2.0 of belt scale is used for industrial control management.Testing accuracy is daily used accuracy.Meanwhile,do technical analysis in the problems of engineering design configuration,installation and testing.There are two design principles of belt scale below.

1、The appropriate configuration of conventional belt scale according to the technical requirements for accuracy,range,weighing object,installation conditions and test methods,control methods and cost level.In the late seventies,early eighties,our cement industry imported the German BMP-belt scales for  technological progress and improving the production process.In order to promote technological progress,and gradually narrow the gap with the world advanced level,learning,absorbing,digesting foreign advanced experience and productive technology is beyond reproach,but it can be sure that foreign manufacturers can not introduce their advanced technology and cutting-edge technologies to us.Causing their nearly eliminated products making another market in China,the blindness introduction caused to repetitive introduction,and it is not precedent in the belt scale industry.

2、Belt scale engineering design principle is designed to obey the production site,rather than requiring the production site subject to design.First we must master the relevant manufacturing level,technical specifications, functions, structure and use of belt scale,etc.The production industries of belt scales in our country is up to dozens of manufacturers,product development and technology updates are faster,so it must conduct a comprehensive study and research purpose.List suitable for belt scale power system characteristics and conditions of coal conveyor belt used in many scales manufacturer,combine the conditions reflected by the users,analyze and compare comprehensively,then write the investigation reports and research reports.Fieldwork contents are:visit exhibitions about relevant aspects of belt scale and force measurement and weighing technology,visit manufacturers that produce and manufacture belt scale weighing sensor,mainly the varieties,specifications and performance,processing technology and equipment of belt scales of the manufacturers,the control device used to debug the whole secondary instrument,the product characteristics.

Belt scale is a mechanical and electrical instrumentation and control one of the four technology-intensive kind of dynamic weighing equipment,the industry applications is wide range,the weighing location mix.People must have some knowledge of scales and measurement techniques to master the national professional standards and test procedures and regulations,routine maintenance and professionalism,ethics is a prerequisite to ensure the proper use of belt scale.
