Integrator for Belt Scales and Weigh Feeders

The BW500 is a full feature integrator for use with both belt scales and weigh feeders. It operates with any belt scale with up to four strain-gauge load cells. It processes belt load and speed signals for accurate flow rate and totalized weight of bulk solids. It can take on lower level control functions traditionally handled by other devices and supports popular industrial communication buses. Its patented load-cell balance function eliminates matching of load cells. The PID function may be used for rate control on shearing weigh feeders—where belt loading is constant—but can also control prefeeding devices. Operating in tandem with two or more weigh feeders, the unit can be used for ratio blending and controlling additives. Batching, load out, and alarm functions are also provided by the integrator.
