| Once upon a time there was a man who had a daughter, who was called Clever Alice; and when she was grown up, her father said, We must see about her marrying. Yes, replied her mother, whenever a young man shall appear who is worthy of her. ... Read more of Clever Alice at Children Stories.ca |  Informational.caPrivacy |

Pyrometers For Molten MetalCategory: 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.
