Test Chain
Test chain calibration is used for testing mechanical belt scales, and to calibrate high capacity electronic belt scales and weighfeeders that cannot be calibrated using material tests.
During the calibration, the test chain is applied to the conveyor belt and is secured at both ends so that the chain remains stationary over the weighing length. The chain rolls on the surface of the moving belt conveyor, providing dynamic scale loading of a known weight value, and thus supplying the calibration reference.
The roller test chain simulates live material loading by causing the belt’s structure to deflect similar to when material is present.
A much greater test load can be applied to high capacity belt scales and weighfeeders because most weighbridge designs can only accommodate a limited number of static weights applied to the suspension. The high capacity test load is especially important on systems using mechanical weighing elements and lever systems because they calibrate the systems with test load values close to normal operating loads.

Test Chain Storage Reel
Test Chain Storage Reel Test Chain Storage Reel Description Test chain storage reels can electronically apply and retract calibration test chains. Storage reels are useful when high capacity test chains are being used to calibrate mechanical belt scales. An electronic geared brake motor rolls the chain onto the belt and over the weigh length. The brake will hold the chain in storage if power fails to the motor. Test chain storage reels are available in multiple compartment styles to simulate different loading conditions on the belt scale.
