Such thermocouples can be considered as the most universal ones. It is recommended to use them both for above-zero and below-zero temperatures. They are rather sensitive and precise, but have a lower cost if compared with their counterparts made of nickel and copper-nickel alloys. Such universality is determined by heterogeneous media where ICTs (iron-constantan) are applied.

Metotechnics Company offers iron-constantan wire for producing thermocouples. For ordering it please call us, send a request via e-mail or order it on our price-list page.

See the corresponding sections of this page for information on certain materials, production methods and applications.

Grades

The products are made of low-carbon steels and CuNiMn 40-1,5 constantan copper-nickel alloys.

The steel contains iron (Fe)(basis) and a low per cent of carbon ©(up to 0.25%). Alloying agents are not added to this material.

Constantan includes 56.1-60.0% of copper (Cu), 39-41% of nickel+cobalt (Ni+Co) and 1-2% of manganese (Mn). The content of the other components is very low.

Chemical composition of CuNiMn 40-1,5 constantan is regulated by GOST 492-2006, the chemical composition of low-carbon steel (iron) - by corresponding standards for the corresponding type of steel.

Production

Iron-constantan wire is made on draw benches by pressurizing the blanks such as large-diameter rods or wire. The whole process is made without heating the blanks so it complies with the principles of cold deformation.

The semi-finished products are annealed for making them flexible.

Iron-constantan thermocouple wire is supplied in a specially selected couple that should give readings that are the closest to the table values. Certain bundles are selected in compliance with a regulated technology. The process of thermocouple selection, gradation and verification is described in article Thermocouples. Types, properties, constructions, production.

The product size, supply condition, properties, measuring range are given in GOST 1790-77, nominal static properties for corresponding thermocouples are given in GOST R 8.585-2001.

Properties

  • Range of measured temperatures: -203 °С - +750 (+1100) °С. The maximum temperature for short-term use is given in brackets.
  • It is operated in oxidation and reduction environment, inert gas or vacuum.
  • Porcelain, quartz, fiber glass, enamels and asbestos are used for electrode insulation.

Application

Semi-finished products made of the described materials are used for producing iron-constantan thermocouples (ICT). They are intended for measuring both below-zero and above-zero temperatures under 1100 °С. In practice, such thermocouples are used in systems where both temperatures occur. In other cases it is better to use chromel-alumel and/or chromel-copel thermocouples. ICTs are used in scientific and industrial equipment.
