Thermocouple Compensating Cables
Thermocouple/Compensating Cables are extension leads widely used in glass industry, low temperature and cryogenic applications, as well as reducing atmosphere environments. These cables are made from different metals but provide similar EMF output in the temperature range of 0 to 100°C.
They are commonly used to connect the thermocouple metal junction to measuring instruments. These compensating cables act as reliable solid conductor leads, ensuring accurate temperature measurement.
Different EMFs are generated using various metal pairs, which are proportional to the hot junction and the measurement point. These cables are available in different color codes, core configurations and sheathing types as per international standards.
Description
Extension 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.
Available Range:
- K – Chromel / Alumel (most commonly used)
- T – Copper / Constantan (for low temperature and cryogenic applications)
- J – Iron / Constantan (used in reducing atmosphere)
- E – Chromel / Constantan (highest EMF output)
- R – Platinum-13% Rhodium / Platinum
- S – Platinum-10% Rhodium / Platinum (very high temperature measurements)
- B – Platinum-30% Rhodium / Platinum (mainly used in glass industry)
Different color codes of cores and sheathing are used as per international practices to identify various thermocouple cables.
