Instrumentation technology is vitally important today since it supports the automation of a wide range of manufacturing factories, the chemical industryand electrical power gene- ration facilities. Engineers who are active in these and ot- her fields need the technical information and support provi- ded by this comprehensive text. Modern instrumentation tech- nology is a constantly-changing kaleidoscope of technologi- cal progress that is keeping pace with the entire field of micro-electronics. This is necessary to keep up with the progress evident in the industries that it supports. As a result, the traditional technology of industrial instruments has evolved into one of comprehensive instrumentation sy- stems for an entire factory or plant. This state-of-the-art book is a handy, single-source reference for information re- quired by engineers in the instrumentation business.
