tailieunhanh - Microcontroller Based Temperature Monitoring and Control

Temperature measurement and control are vital in many industrial processes. Accurate control of the temperature is essential in nearly all chemical processes. In some applications, an accuracy of around 5-10~ may be acceptable. There are also some industrial applications which require better than 4-1 ~ accuracy. | Microcontroller Based Temperature Monitoring and Control x IF Dogan Ibrahim J ISBN 0750655569 Publisher Elsevier Science Technology Books Pub. Date September 2002 Preface Temperature measurement and control are vital in many industrial processes. Accurate control of the temperature is essential in nearly all chemical processes. In some applications an accuracy of around 5-10 C may be acceptable. There are also some industrial applications which require better than 1 C accuracy. Temperature sensors come in many different forms and a number of techniques have evolved for the measurement of temperature. There are new forms of sensors which require no contact with the medium whose temperature is to be sensed. The majority of sensors still require to touch the solid liquid or the gas whose temperature is to be measured. Four technologies are currently in use thermocouples TCs thermistors resistance temperature detectors RTDs and IC sensors. This book is an engineer s guide to planning designing and implementing temperature based control systems using a microcontroller. It will also prove invaluable for students and experimenters seeking real-world project work involving the use of a microcontroller. Engineers involved in the use of microcontrollers in measurement and control systems will find it an invaluable practical guide providing design principles and application case studies backed up with sufficient control theory and electronics to develop their own systems. A basic mathematical and engineering background is assumed but the use of microcontrollers is introduced from first principles. Exercises are provided at the end of most chapters to enable the reader to practice their knowledge. This book is essentially in two parts temperature measurement and temperature control. The early chapters are about the temperature sensors and their use to measure temperature. The basic theory behind the various temperature sensors and practical working microcontroller based .
