PFA insulated chromel alumel thermocouple wire 1.0mm2
The thermocouple compensation cables can also be termed as instrumentation cables, since they are used for process temperature measurement. 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.
Type K thermocouple wire has strong resistance to oxidation than other base metal thermocouples. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:
(1) Alternatively oxidizing and reducing atmosphere.
(2) Atmosphere with sulphur gases.
(3) Long time in vacuum.
(4) Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere.
