Components for Pneumatic Control Instruments: The Static and Dynamic Characteristics of Pneumatic Resistances, Capacitances and Transmission Lines provides a list of problems necessitating a detailed study of the characteristics of restrictions and chambers. This book discusses the problems that arise during the development, improvement, and use of pneumatic instruments. Organized into four chapters, this book begins with an overview of the theory and design of restrictions. This text then considers the main characteristics of restriction processes, giving the features of the restrictions used in different pneumatic control and regulating instruments. Other chapters deal with the static characteristics of pneumatic chambers with restrictions of various types. This book discusses as well problems of the dynamics of pneumatic chambers. The final chapter deals with the characteristics of log pneumatic lines and of systems with distribution parameters. This book is a valuable resource for aircraft engineers and readers who wish to understand the problems of the theory and design of elements of pneumatic control and regulating instruments.

Progress in Water Technology, Volume 6: Instrumentation Control and Automation for Waste-Water Treatment Systems contains the proceedings of the International Association on Water Pollution Research Workshop on Instrumentation Control and Automation for Waste-water Treatment Systems, held in London in September 1973. Contributors review major advances that have been made in instrumentation control and automation of wastewater treatment. This volume consists of 70 chapters organized into six sections. The work of the Directorate General Water Engineering in the Department of the Environment in the UK and the Environmental Protection Agency in the United States with respect to promotion of instrumentation, control, and automation for wastewater treatment systems is first discussed. This discussion is followed by a chapter that describes the effects of water pollution legislation in The Netherlands on the selection of wastewater treatment plants and their consequences for consulting engineers regarding process, technical, and economical feasibility. A real-time water quality management system for a major river in Pennsylvania is also considered, along with effluent control and instrumentation in Europe. The chapters that follow focus on instrumentation and control problems in the design of a modern sewage works; installation of field equipment in automated process control systems; process control for biological treatment of organic industrial wastewaters; and the use of computers to control sewage treatment. This book will be of interest to authorities, planners, and policymakers involved in wastewater treatment and water pollution control.

PC Based Instrumentation and Control is a guide to implementing computer control, instrumentation and data acquisition using a standard PC and some of the more traditional computer languages. Numerous examples of configurations and working circuits, as well as representative software, make this a practical, hands-on guide to implementing PC-based testing and calibration systems and increasing efficiency without compromising quality or reliability.

Pneumatic and Hydraulic Components and Instruments in Automatic Control covers the proceedings of the International Federation of Automatic Control (IFAC) Symposium. The book reviews papers that tackle topics relating to the use of pneumatic and hydraulic equipment in automatic control. This text discusses topics such as dynamic behavior analysis of pneumatic components by numerical techniques and application of bond graphs to the digital simulation of a two-stage relief valve dynamic behavior. Topics including mathematical modeling of cavitation in hydraulic pumps; pro and contra electro-fluid analogies in digital simulation of fluid circuits; and improvement in accuracy of pneumatic delay are covered as well. This book will be of great use to researchers and professionals whose work involves the designing of automatic control systems.
