For temperature conditions above 1100°C, tungsten materials are used for making thermocouples. The position at which the thermocouple is placed plays a governing role in precise measurement during analysis.

Why is chromel and alumel used in thermocouple?

WebThis example is an exercise in the use of thermocouple tables, but it also serves to illustrate the large errors that can arise if thermocouples are used incorrectly. In a particular industrial situation, a chromel-alumel thermocouple with chromel-alumel extension wires is used to measure the temperature of a fluid. WebSep 7, 2024 · In addition to thermocouples, alumel is used for thermocouple extension wire. In thermocouples, the alloy is used with chromel to fabricate type K thermocouples. Constantan: This alloy usually consists of 55% copper and 45% nickel. Its greatest advantage is a constant resistivity over a wide spectrum of temperatures. basalamah
