This book provides a comprehensive view of what is needed to take advantage of the latest developments in smart and wireless temperature measurements and control strategies. A fundamental understanding of the capabilities of temperature sensors and the advances in wireless technology are provided. The effect of sensor types and installation on measurement accuracy and speed is detailed. Guidance is provided for making the commonly faced choice between thermocouples versus resistance temperature detectors. The temperature control requirements for various types of equipment are discussed. Control systems to meet specific objectives are provided. The appendices provide solutions to the exercises, data important for heat transfer, a unification of controller tuning methods, and equations to estimate process dynamics.
