Thermocouple compensation wire cables type
Equivalent use: IEC584-3 "Thermocouple Part III - compensation wire" international standards, product quality is better than B4989-85 "thermocouple with compensation wire" national standards. Insulation layer and the use of imported high-quality fluorine plastic sheath, and the use of the overall continuous extrusion of new technology, the product has excellent acid, alkali, wear-resistant and non-combustible extension of the performance can be immersed in water long-term use. The use of temperature at -60 ~ 205 ~ 260 ℃, belonging to the contemporary international advanced level. Model and name:
Compensating wire type according to product variety is divided into: SC, KC, KX, EX, JX, TX.
Wherein: a) the first letter of the model corresponds to the index number of the thermocouple;
B) The letter "X" indicates the extension type compensation wire (type)
C) The letter "C" indicates the compensation type compensation wire (type)
Note: SC-type compensation wire can be equipped with R-type thermocouple number.

1, the compensation cable by product variety is divided into: SC BC KC KX JX TX EA, where the
letter "×" that extended compensation wire, letters
"C" means the compensating cable whose thermoelectric potential and resistance value conform to the
following table:
2, compensation cable insulation test insulation resistance at 40 ℃ water after 24 hours is not
less than (10 meters) 25MΩ.
3, the compensation cable heat aging 24 hours after 5 times the diameter test, the voltage test
5000V / 1min does not breakdown.
