DatasheetSiemens Milltronics BW500 and BW500/L is a full feature integrator for use with both belt scales and weighfeedersSiemens Milltronics BW500 and BW500/L operate with a belt scale and a speed sensorBelt load and speed signals are processed for accurate flow rate and totalized weight of bulk solids. BW500 can take on lower level control functions traditionally handled by other devices, and it supports popular industrial communication buses. Its proven load cell balance function eliminates matching of load cells. The PID function may be used for rate control on shearing weighfeeders – where belt loading is constant – but can also control pre-feeding devices.

Typical applications: for use in basic belt scale or weighbelt applications
Operating in tandem with two or more weighfeeders, the BW500 may be used for ratio blending and controlling additives. Batching, load out, and alarm functions are also provided by the BW500.
