Placing The Thermo-couples






Category: PYROMETRY AND PYROMETERS

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.
