Dedicated to you, my colleagues, the instrument and process control engineers. I hope that by applying the knowledge found on these pages you will make our industries more efficient, safer, and cleaner, and thereby will not only contribute to a happier future for all mankind but will also advance the recognition and respectability of our profession.

Instrumentation and process control can be traced back many millennia. Some of the early examples are the process of making fire and instruments using the sun and stars, such as Stonehenge. The evolution of instrumentation and process control has undergone several industrial revolutions leading to the complexi- ties of modern day microprocessor-controlled processing. Today’s technological evolution has made it possible to measure parameters deemed impossible only a few years ago. Improvements ...
