This book describes the fundamental principles of electronic weighing, beginning with the theoretical background of the basic components and continuing with the theoretical formulas to calculate the weighing accuracy in different applications, including the influence on accuracy of external disturbing forces. It also describes the layout and optimum composition of weighing systems for static weighing and batching, in-motion weighing, belt conveyor weighing and flow control, as well as counting and checkweighing scales. Complete technical specifications are included, which, supplemented with relevant technical data, can serve as masters for procurment of the equipment for twelve typical industrial weighing applications. Testing principles and procedures for test reports are detailed, covering all kinds of static weighing and batching systems, as well as belt conveyor scales and dosimeters. Written for practitioners, this book will give engineers and managers in the chemical, iron and steel, pulp and paper and other industries an awareness of the basic technology, an appreciation of the range of its application, and an understanding of the performance that can be expected.
