EBOOK - Integrators Milltronics BW500 and BW500L - Operating Instructions (SIEMENS) | Cộng đồng Kỹ thuật cơ điện Việt Nam EBOOKBKMT

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.
