Pyrometers For Molten Metal






Category: PYROMETRY AND PYROMETERS

Pyrometers for molten metal are connected to portable thermocouples
as in Fig. 132. Usually the pyrometer is portable, as shown in
this case, which is a Brown. Other methods of mounting for this
kind of work arc shown in Figs. 133 and 134. The bent mountings
are designed for molten metal, such as brass or copper and are
supplied with either clay, graphite or carborundum tubes. Fifteen
feet of connecting wire is usually supplied.

The angle mountings, Fig. 134, are recommended for baths such as
lead or cyanide. The horizontal arm is usually about 14 in. long,
and the whole mounting is easily taken apart making replacements
very easy. Details of the thermo-couple shown in Fig. 132 are given
in Fig. 135. This is a straight rod with a protector for the hand
of the operator. The lag in such couples is less than one minute.
These are Englehard mountings.
