VPG / Model 1410 Load Cell for Rotary Filling Machines

VPG / Model 1410 Load Cell for Rotary Filling Machines

The load cell model 1410 is a fluid damped load cell designed to be used in rotary filling machines. The load cell alleviates many of the problems encountered when conventional load cells are used in rotary weighing machines. Due to a patented damping system, typically setting times of 700 ms are reduced to less than 300 ms (depending upon conditions) significantly reducing cycle times and increasing throughput capabilities. Centrifugal forces are handled in such a way that their effect on output is very small. The 1410 provides excellent isolation of base vibrations.
