Type T thermocouple cable TPX and TNX Fiberglass insulated
TYPE T (Copper vs Constantan) is used or in an oxidation, inert or reduced atmosphere or in vacuum. It has highly corrosion with atmospheric moisture and condensate corrosion, and high stability is exhibited at low temperatures. It is the only type with error-limited uses for low temperature temperatures.

In actual temperature measurement, usually there are long measuring distance with the measuring device, a thermocouple compensation wire is generated to compensate the temperature difference caused by the temperature change between the measuring device and the thermocouple connecting piece.
The compensation cable has the following advantages: improving thermocouple temperature measurement line physical properties and mechanical properties; improving the measurement line flexibility and making the connection convenient by using multi-strand core or small-diameter compensation wire; easy to shield external interference; reducing measuring lines cost.
Package
Thermocouple Cable Grade
A:Extension Grade Cable
Whose wire composition is totally as the same as the thermocouple wire, remarked by the letter"X"after the thermocouple symbol number, such as"KX""JX""TX"
B:Compensation Grade Cable
Whose wire composition is different from the thermocouple wire, but its wire electromotive force (EMF) value is the same as thermocouple wire only at 0-100ºC or 0-200ºC. It remarked by the letter"C"after the thermocouple symbol number, such as"KC""JC""TC"
| Performance | Extension Grade | Compensation Grade |
| Material | Same as thermocouple | Different from thermocouple |
| EMF Value Feature | Same as the thermocouple's at certain temperature range | Same as the thermocouple's |
| Deviation Curve | Nonlinear, varies with temperature | Linear |
| Working Temperature Range | Limited(usual at 100ºC) | Unlimited(depend on insulation material temperature bearing) |
| Line Resistance | Low resistance | High resistance |
| Compensation Contact Interference | Different contactor material may cause interference | None |
| Accuracy | Low | High |
| Price | Low | High(about 1-2 times higher) |
