Reflections on Pyrometer Design and a Description of a New Radiation Pryometer.

JSGT 1924 V08 T117-T138

The value of pyrometers in heat-treatment problems is now too well recognised to need discussion, and to-day the matter of chief concern to the engineer or other pyrometer user lies in the choice of the most effective tool or instrument for his purpose. Electrical forms of pyrometers have proved their superior merit over other forms for the majority of high temperature applications; and in particular the thermo-electric type takes predominant place, within its sphere of practical usefulness. The reason is not far to seek; for the simplicity of the principle, the elimination of complex accessories, the freedom from constant and troublesome attention, and the accuracy obtainable with the practical form of thermoelectric pyrometer at once appeal to the workman, the practical manager, and the technical experimenter alike.
