1Electronic scale calibration weight/stainless steel chain code belt scale usageTechnical description: The cyclic chain code device of Xuzhou Lipus Company is easy to operate and has a high degree of automation. It can run automatically or manually. The detection data can be directly entered into the instrument and computer without intermediate links, and the calibration data can be obtained directly. It can be connected to the belt scale to automatically modify the parameters of the belt scale, which is extremely convenient.

2. The working principle of cyclic chain code: The chain code ring is pressed onto the belt by the movement of the electric push rod, and the chain code ring runs smoothly with the belt. When the chain code circle rotates one circle, the weight acting on the belt scale is the standard weight of the chain code circle. When the chain code circle continues to rotate N circles, the instrument transmits the signal from the speed sensor to obtain the weight acting on the belt scale=number of circles x standard weight. The display value of the belt scale instrument should be adjusted based on the display value of the cyclic chain code instrument, in order to achieve dynamic nuclear testing of the belt scale.

How to quickly and correctly select weight grades

The grade of weights is an important factor in purchasing weights. The higher the grade, the more expensive the price will be, and the higher the precision of weights, the cheaper the price. However, the lower the grade, the lower the precision of weights. When purchasing weights, the grade must be determined.

as follows

1. Choose E2 grade non-magnetic stainless steel weights for 100000 parts per square meter

2. Choose E2 grade or F1 grade non-magnetic stainless steel weights at a rate of 10000 square meters

3. Choose F1 grade non-magnetic stainless steel weights on a per thousand basis

4. Choose F2 grade stainless steel weights at a percentage level

5. Choose M1 grade stainless steel weights or M1 grade cast iron weights for 10% flatness
