Characteristics
The thermocouple cable are formed by the combination of 2 different materials and are identified with a letter (J, K, S, T), each of them is used for a temperature range.
When the conductors and the thermocouple's wires are of the same nature, it is called extension cable, and when the conductors are of a different nature to that of the thermocouple's wires, a compensation cable.
Application:
Cable de compensación son para la medida de temperatura generada por una fuente de calor y detectada por un termopar a una distancia mayor.
Datos Constructivos:
The cable can insulate with different types for different temperature ranges. The types of insulation we made is:
KAPTON – Similar of FEP, but with the advantage that it handles a range from -267 a 350ºC.
FIBERGLASS – Very good for temperature 400ºC.
BRAID FIBERGLASS - We find that it is one of the most common insulators and the difference with the previous one is that the mesh protects the cable so that it does not fray easily, as well as helps protect it from shocks, which helps to extend its useful life.
PVC - Temperatures up to 105ºC, is economical, supports acid solutions, humid environments, they are normally anti-flame.
