Typical process weighing applications include batch/blend, reactor, and mixing vessels where two or more "ingredients" are combined to produce a final product. Although actual processing varies greatly from product to product and company-to-company, the usual procedure entails adding each ingredient to the process vessel separately, based upon recipe designated weight values. Once all essential ingredients are present in their predetermined quantities, processing is initiated by adding a catalyst, beginning a motorized mix/blend interval, or both. Precision processing requires systems that remain insensitive to side and end loads introduced by integral process equipment (motors, mixers, etc.) and thermal expansion caused by the vessel heating.
