Manual chaincode

CLM series belt scale manual chain code verification device

 System Overview 

Electronic belt scale verification chain code-dynamic verification measurement accuracy is high (static 3/1000, dynamic 1/1000), easy to operate, does occupy the site, that is, it reduces safety labor, greatly improves work efficiency. It saves the investment of the enterprise compared with the physical verification device "electronic hopper scale", the "electronic hopper scale" has a large equipment area, occupies a large space, is troublesome during verification, the cost is high. The CLM series check chain code is the first choice for solving belt scale check. If equipped with an automatic retractable winch device, the chain code can be automatically operated during the verification process, which greatly improves the work efficiency.

The belt chain manual chain code CLM series calibration device conforms to the provisions of the National Measurement Verification Regulations of the People's Republic of China JJG1995-2002. It is an analog load standard can be used as a calibration standard for electronic belt scales weighing feeders. It can easily calibrate correct the measurement accuracy of electronic belt scales.

 working principle 

After the electronic belt scale is zeroed, the weight of the standard weight dynamically simulates the state of the material when the belt is running. The chain code simulates the load of each meter of material on the belt is placed on the running belt. Stretched to prevent deviation sliding with the belt, the length should be able to cover the weighing roller the two sets of rollers of the electronic belt scale. Record the length of one revolution of the belt the number of revolutions, which is the product of the nominal value of the chain code as the "reference value". The chain code transfers the weight to the weighing sensor through the scale body. At this time, the running speed of the belt is constant, the weighing instrument calculates displays the instantaneous cumulative amount. The cumulative quantity of the weighing instrument is compared with the reference value to determine whether the actual error of the electronic belt scale is within the required range, verify whether its measurement accuracy is qualified.

 System Components 

    CLM chain code calibration device is composed of roller ball, chain, inner outer connecting plate hanging ring.
