Accurate belt scale integrators for increased efficiency in simple and complex applications

24.01.2011
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 Milltronics BW500 comes with five relays, offers additional PID control and batching in its functionalities and is specially designed for complex applications.


The Milltronics BW500 and BW500/L belt scale integrators of the Siemens Industry Automation division provide unequaled accuracy based on the patented electronic load cell-balancing feature, providing improved efficiency in simple and complex applications.

First launched in 1999, Milltronics 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), the BW500 processes belt load and speed signals for accurate flow rate and totalized weight of bulk solids. The new 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 make them a world leader in system accuracy. Used with the MMI belt scale, Milltronics BW500 is ideal 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.

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
