Introduction
Milltronics BW500 and BW500/L
Milltronics BW500
The Milltronics BW500 is a full-featured integrator for use with belt scales and
weighfeeders. The speed and load signals from the conveyor and scale, respectively, are
processed to derive rate of material flow, and totalization. The primary values of speed
and load, and the derived values of rate and total are available for display on the local
LCD, or as output in the form of analog mA, alarm relay and remote totalization.
Milltronics BW500/L
The Milltronics BW500/L is an integrator for use in basic belt scale or weighbelt
applications. The speed and load signals from the conveyor and scale, respectively, are
processed to derive rate of material flow, and totalization. The BW500/L does not include
the advanced feature set for control.
Milltronics BW500 and BW500/L features
BW500 and BW500/L support Siemens Milltronics Dolphin Plus software and Modbus
protocol on the two RS-232 ports and the RS-485 port for communication to customer PLC
or computer. BW500 and BW500/L also support Siemens SmartLinx®for popular
industrial communication systems.
