Armored cables are made of different material conductors packed in metal sleeves with insulating materials and processed into a bendable solid assembly. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads. They are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments. are armored thermocouples.
Armoring is divided into steel tape armoring (22, 23), thin steel wire armoring (32, 33), thick steel wire armoring (42, 43).
