PLACING THE THERMO-COUPLES
FIG. 115.—Potentiometer ready for use.
The following illustrations from the Taylor Instrument Company show different applications of the thermo-couples to furnaces of various kinds. Figure 118 shows an oil-fired furnace with a simple vertical installation. Figure 119 shows a method of imbedding the thermo-couple in the floor of a furnace so as to require no space in the heating chamber.
Various methods of applying a pyrometer to common heat-treatment furnaces are shown in Figs. 120 to 122.
