With the arrival of the era of industrialization production,industrial automation system has been an unprecedented rapid development,as an indispensable part of industrial automation,belt weigh scale has been widely used in production.It mainly consists of scale aircraft,roller,conveyor belts,force sensors,speed sensors and measuring circuit.The applications of belt weigh scale in industry is mainly in the following two aspects:

1、Industrial production generally requires the continuity and reliability of the production.As a kind of weighing apparatus,the advantage of belt weigh scale is continuity and reliability,so belt weigh scale meet the demand of industrial automation for the piece of measurement,especially in recent years,with the rapid development of digital sensor technology and electronic technology,the accuracy and reliability of belt weigh scale has been greatly improved.

2、Industrial automation puts forward higher requirements for the communication ability of weighing apparatus.In industrial automation system,there are close ties between each site,between site and sensor,between site and equipment,between sensor and equipment,the various departments are no longer independent,but part of the whole system, so it requires very convenient communication and data exchange between each equipment,sensor and departments.

So it is very important to test belt weigh scale before leaving the factory,then how do we perform factory tests on belt scale,so what are the main items to test when testing belt weigh scale,let's take a look.

1、The first thing we should test the installation belt length of belt conveyer.

2、Then we should test whether there is any problem of the entire belt meter in using process.
