Measurement and control basics (3^rd Ed.)

Each chapter begins with basic definitions and mathematical concepts that allow readers to become well-versed in the principles necessary to understand the variables that affect process control systems. New features in the third edition include coverage of advanced control-loop tuning methods, magnetostrictive displacement pressure transducers, infrared, microwave, nuclear, radar and thermal level instruments, radiation, optical, and infrared pyrometers, oxidation-reduction potential measurement, and a completely updated chapter on programmable logic controllers, PC-based control, and human-machine interfaces.The book also includes, for the first time, solutions to exercises that make it more suitable for self-study. The text introduces process and instrument drawings to illustrate concepts. An appendix outlines standard graphic symbols used in piping and instrumentation diagrams.
