The reader would typically be involved in the design, implementation and upgrading of industrial control systems. Mathematical theory has been kept to a minimum with the emphasis throughout on practical applications and useful information.This book will enable the reader to:* Specify and design the loop requirements for a plant using PID control* Identify and 410 0$aPractical professional books from Elsevier. 606 $aProcess control 606 $aProduction engineering 608 $aElectronic books. 615 0$aProcess control. 615 0$aProduction engineering. 676 $a629.8 700 $aAltmann$b Wolfgang$0867600 701 $aMacdonald$b Dave$f1942-$0627440 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910457668603321 996 $aPractical process control for engineers and technicians$91936414 997 $aUNINA
