Thermocouple Compensating Cable

In the cables, varied EMFs are generated with different metal pairs that are further proportional to hot junction and the point where it is measured. All these cables are available in different color codes or cores and sheathing as per the international standards.

Extention leads of different metals but having similar EMF output between 0°c to 100°c connected between Thermocouple metals junction and the measuring instruments are called compensating cables which are generally recommended as solid conductor leads.

• K-Chromel/Alumel-Most commonly used
• T-Cooper/Constantan for low temperature & cryogenic applications
• J-Iron/Constantan used in reducing atmosphere
• E-Chromel/Constantan Highest EMF output
• R-(Plantinum-13% Rhodium)/Platinum & S-(Platinum-10% Rhodium) /Platinum very high temperature measurements.
• B-(Platinum-30% Rhodium)/Platinum mainly used in glass industry Different colour codes of cores and sheathing as per international practices are used to denote the various thermocouple cables

Thermocouple/Compensating Cables are the extension leads mostly used in glass industry, low temperature & cryogenic applications and reducing atmosphere. The cables are made from different metals but with similar EMF output in the range of 0 to 100 degree Celsius. Widely used to connect the thermocouple metal junction and measuring instrument, these compensating cables are considered as the best solid conductor leads.

Different metal pairs generate different emfs which is proportionate to the hot junction and the point where it its measured. Common combination of thermocouple metals.
