Thermocouple Type K Extension Cable For Temperature Compensation

Thermocouple Type K Extension Cable for Temperature Compensation

The compensation wire models are divided into SC, KC, KX, EX, JX, TX according to the product variety.

Among them: a) The first letter of the model corresponds to the graduation number of the thermocouple;

b) The letter "X" represents the extended compensation wire (type)

c) The letter "C" represents the compensation type compensation wire (type)

Note: SC type compensation wires can be equipped with R-type indexing thermocouples.

• Thermocouple Extension Wire

Type K Extension Cable 0.5*2 red black pvc insulation with pvc sheath. The conduct is thermocouple type K material which is nickel-chrome with nickel-siliconor nickel-aluminum. The construction is similar to pair instrumentation cable but the conductor material is different. Thermocouples are used in processes to sense temperature and is connected to the pyrometers for indication and control. The thermocouple and pyrometer are electrically conducted by thermocouple extension cables / thermocouple compensating cables. The conductors used for these thermocouple cables are required to have similar thermo-electric (emf) properties as that of the thermocouple used for sensing the temperature.

Basically, Fine Wire Thermocouple grade wires are used to make sensing points of thermocouples. However, a Thermocouple Extension Wire is only used to extend a thermocouple signal back from the probe to the instrument reading it. A thermocouple Extension Cable is used in lower ambient temperatures. It may pass a signal representing a higher temperature than it received from the probe. However, Type K Thermocouple Extension Wire may not be physically exposed to that high temperature. A Stranded Thermocouple Wire can be used as an extension wire but an extension wire cannot be used in a Flexible Thermocouple Wire as a sensing point. The usable length of these wires differs based on numerous factors.
