Resource guide: Weighing systems

June 18, 2018
Control's monthly guide brings you invaluable industry information to stay up to date on the latest trends and developments

Tank, custom scales book

This 150-page book, "Weigh module systems: engineering guidelines for customized scales," provides information on applications with load cells and weigh modules to help readers engineer effectivel weighing and inventory control systems. It covers: assessing tank, platform or conveyor system performance needs and setting performance criteria; engineering calculations that account for wind, seismic, shock and thermal effects; designing tank piping-connections to address support structures and foundations; qualification guidelines for structural, foundation, electrical and mechanical issues for best accuracy; and engineering specifications for compression, tension, static and dynamic load cell applications.

Bulk scale maintenance

Two blog articles, "Keeping your bulk material handling systems in balance—maintain your scales" and "Do your idler rolls meet the total indicated run out (T.I.R.) tolerance?," by Bill Ripka at ThermoFisher Scientific shows users how to give their scales, scale areas, belt conveyors and equipment the care they deserve. The first article also has a maintenance checklist chart. Read the blogs here.

Hidden costs of inaccuracy

This white paper, "The hidden and surprising costs of weighing inaccuracy," by BLH Nobel provides information to help process automation professionals define their weighing needs, and identify the cost of reduced weighing accuracy in their plants. Topics include: how slight improvements in weighing accuracy can provide significant savings; signs that a weighing system may be incurring excessive costs; difference between accuracy and repeatability; and performing statistical analysis of accuracy and lifecycle impact with Syscalc, a sizing software system from BLH Nobel.

Load cell wiring app

What's reported to be the first mobile app for the weighing industry is based on the popular "Load Cell Wiring Guide" that helps technicians decipher the wiring colors of almost any given load cell brand and model. It's now available as a free mobile application for smart phones, tablets and PCs. Users simply select the brand and model for a load cell, and the app does the rest, showing which wires represent excitation, signal and sense lines. It's available here.
