Siemens Industry Automation division has improved its Milltronics BW500 belt scale integrator, and added a new version, Milltronics BW500/L, to its portfolio. The new version, developed specifically for simple applications with belt scales, has two relays. It calculates rate, totalized weight, belt loading and belt speed. The relays are programmable SPST form A contacts rated 5A at 250 V AC non-inductive, reversible. An automatic calibration function saves time during operation. Both versions store parameter data in a non-volatile Flash memory; measurement and control data is always available, even if the unit loses power. The standard BW500 comes with five relays, offers additional PID control and batching in its functionalities and is specially designed for complex applications.
The BW500 is widely used in the food, cement, aggregate and mining industries. Operating with any belt scale or weighfeeder with up to six strain gauge load cells or LVDT (linear variable differential transformer), integrator processes belt load and speed signals for accurate flow rate and totalized weight of bulk solids. The BW500/L can be used with one or two-load cell belt scale systems. Both versions can be connected to industrial networks via Profibus DP, Allen Bradley RIO and DeviceNet. They are also compatible with Sitrans RD500 remote data manager.
Both versions’ patented electronic load cell-balancing feature ensure system accuracy. Used with the MMI belt scale, they are suited for fast-moving belts, short idler spacing, and light or uneven belt loading. Combined with Milltronics MSI and MMI belt scales and a speed sensor, Milltronics BW500 has various approvals for custody transfer and legal for trade applications, including OIML (International Organization of Legal Metrology), MID (Measuring Instruments Directive), NTEP (National Type Evaluation Program), and Electronic Indicator/Totalizer approval from Measurement Canada.
