Summary Weighing technology by its very nature suggests something solid and substantial, which is exactly what you get from Siemens - and a whole lot more. From the rugged requirements of a mine to the delicate measurements of pharmaceutical suppliers, Siemens weighing technology provides accurate weight measurement whether the material is on the go or standing still. The unmatched performance of the Siemens Milltronics Single Idler (MSI) leads the way, supported by the whole Siemens line of belt scales, weighfeeders, and flowmeters. These contact instruments provide the data which is then interpreted by Siemens integrators like the SITRANS BW500 and the SIWAREX FTC module. Siemens weighing solutions are supported by peripheral devices and equipment like speed sensors, test chains, and the Milltronics Weight Lifter (MWL). Furthermore, solutions are often custom designed by Siemens technical staff and application engineers to ensure optimal performance. Siemens provides complete weighing solutions for many industries from food and beverage to pharmaceuticals and environmental systems. However, the mining, aggregate, and cement industry is a primary focus where Siemens rugged reliability and accuracy play a key role. When experts ask about the best in the weighing field, the answer is clearly Siemens
