Thermocouple Cables, MIMS

Techno Instruments not only manufactures temperature sensors since 1994, but also is completely committed to provide complete solution to problems associated with heat measurement. With state-of-the-art R&D facilities, the company is vigorously emerging as one of the main solution providers in the field of temperature measurement. Its policy is to maintain an effective quality program in order to provide products and services that meet and exceed customers? requirements, in conformity with regulatory requirements, internationally recognised quality standards and industry accepted practices. The mineral insulated metal sheathed (MIMS) thermocouple technology has brought about a revolution in the TE industries as it has clear winning edge over conventional ceramic twin bore insulator thermocouples. Manufacturing process: MIMS cables are manufactured by using a higher diameter tubes and conductors. The conductors are inserted into metal pipe. The conductors are properly spaced in the pipe by using crushable MgO blocks. These MgO blocks provide insulation between the conductors as well as with the wall. Also these blocks maintain the geometry, i.e., the position of conductors. The operation required to manufacture MIMS cable are: cleaning of tubes, insertion of conductor into the bocks, hot filling (i.e., insertion of conductors along with the blocks into the pipe), swaging (this operation crush the MgO blocks), drawing (the diameter is reduced by successive drawing which also ensures compact powder around the conductors), inter pass annealing (various annealing are required to achieve the metal properties back which are disturbed in drawing process. This annealing is conducted in controlled environment to retain the chemical properties of the sheath material), testing, packing and finishing.
