Kerlin T.W. Practical Thermocouple Thermometry

International Society of Automation (ISA), 1999. — 127 p.Temperature is the most commonly measured quantity in industry, and thermocouples are used to make most of these measurements. There is a tremendous incentive to optimize the selection, installation, and use of thermocouples. Thermocouples have been in use for many years, millions are in service, and manufacturers offer a wide range of thermocouples and powerful instrumentation to indicate, record, and/or control temperature. Nevertheless, there is a general lack of understanding about the basic principles of thermocouple thermometry, and suboptimal measurements are commonplace (often affecting the performance of the monitored process, but hidden because measurement errors are not known).
This book provides a resource to help the user to select, install, and use thermocouples properly after a few days of study. Every effort has been made to include information needed for this and no more. Of course, this runs the risk that something will be left out that is crucial for some readers. Information is provided on where to get information for those who want to dig deeper.Fundamentals.
