We hope that you liked our first blog of our monthly series 'Cable Designers Guide'. In case you did not get the chance to go through it kindly click on the link to read it.  Here we will provide more information about Thermocouple cables.  When a junction of two dissimilar metals is heated, an emf is generated and it is the proportional to the temperature difference between the hot junction and the point where it is measured. This principle is universally used in the industry to measure and control the temperature in process. The junction is know as Thermocouple.  The follow types of Thermocouples have been standardised across the world with relevant standards being ANSI, BS, IEC & IS. Thermocouple Type +ve conductor -ve conductor Working temperature range Limits of error K - Extension Chromel Alumel 0 to 1100 °c +/- 2.2 °c   K - compensation Copper Constantan 0 to 1100 °c +/- 2.2 °c T - Extension  Copper...

The following checklist will assist you to completely specify the cable you want: A. Number and gauge of conductors B. Specification type of wire (IS 1554, IS 7098 etc). C. Coding of conductors or subcables, striping or numbering, if any. D. Tape barrier, used as first mechanical protective layer. Can be of Vinyl, Mylar, Tedlar, Polyethylene, or paper-fiberglass laminates. E. Type of electrical shielding or mechanical armour. F. % coverage required for electrical shielding G. Type of outer jacket material. H. Color of outer jacket, sheath markings. I. Wall thickness of outer jacket. J. Necessary physical or environmental requirements, see below. K. Minimum and maximum overall diameter. Physical Requirements 1. Length, tolerance; Diameter, tolerance. 2. Overall tensile strength, if applicable. 3. Weight limitations. 4. Minimum bend radius. Environmental Requirements 1. Minimum and maximum operating temperatures. 2. Physical abuse: ...
