Technical specifications

4,Automatic turn-up and pay-off winch device of optinal chain code.

3, Structure is easier than objecr calibration device,cost is low,it is near object than weights-hoist.

2,Structure is reasonable,operation is convenient.

1,Accuracy is high

Main features

Through link plate,the roller wheels which array quality is the same connect a whole link.When testing,put the roller wheel above the belt,the 2 sieds are fixed on the pillar.When belt conveyor starting,the roller wheel turns on the belt in situ,analog materials run state when passing the belt,resulting in weight through calculation,comparing with weighing value of weigh integrator.,so as to calibrate.

It consists of roller wheel,link plate,inner and outer margin plate,link eye,etc,according to design type,it falls into A type and B type.

Working principle

After installing automatic turn-up and pay-off winch device,it is more convenient for calibrate belt scale and weigh feeder.

PLJ Rolling chain code checking device meets the specifications of JJG650-90 of PRC,which is a kind of simulation load standards,can be used as a calibration apparatus for belt scale and weigh feeder dynamic checking.
