Excerpt from Practical Pyrometry: The Theory, Calibration, and Use of Instruments for the Measurement of High Temperatures
The day is already past when foundrymen and steel workers de pend upon the eye to judge the temperatures of their product in the various stages of its heat treatment, when makers of ceramic products depend upon the indication of fusible cones, and When Operators of cold storage plants are content to Observe numerous thermometers scattered throughout their establishments. The requirements of modern industrial processes and the severe com petition of commercial enterprises now require not only more precise knowledge of temperatures, but in many cases also re quire a continuous automatic record of the temperature state extending over an interval of time.
Several years ago, anticipating the need by technical students of a Course in High Temperature Measurements, the work of testing the various methods and apparatus was begun. After three years devoted to this survey, a course was organized and Offered. It was received with such favor that it was made a required subject in the plan of study for students of chemical engineering at Purdue University. Each year since then, a new edition of Notes, in mimeographed form, has been put into the hands of the students. It has now been thought proper to put into more readable and permanent form the results of this experience.
