While effective control of temperature loops is extremely important, achieving that control can be difficult because of thermal lags in both the process and measurement. In a properly tuned temperature loop, control errors can often be an order of magnitude less than those seen. This book provides a step-by-step approach for analysis of all the factors that affect the control of temperature loops, including major sources of measurement errors. Tuning guidelines are introduced that account for slow process, sensor, and poor valve response. The advantages and disadvantages of new methods for feedback control and autotuners are discussed. Suggestions for improving control of temperature loops are also provided. Contents: Measurement error controllers temperature loop analysis exchangers reactors columns vessels, desuperheaters, dryers, kilns, calciners, crystalizers, extruders, chambers and rooms. Appendices include: convective heat transfer coefficients density, heat capacity and conductivity data emissivity data feedback equations extruder model subroutine and estimate of dead time from dead band.
