About this product:
Thermocouple
Composition: A thermocouple is a temperature sensor made of two
dissimilar metal wires joined at one end (the measuring junction).
The other end is connected to a measuring instrument.
Working Principle: Based on the Seebeck effect, where a voltage is
generated when there is a temperature difference between the two
junctions of the metals.
Types: Common types include:
Type K (Chromel-Alumel): General-purpose, wide temperature range
(-200°C to 1260°C).
Type J (Iron-Constantan): Lower temperature range (-40°C to 750°C).
Type T (Copper-Constantan): Cryogenic applications (-200°C to
350°C).
Type R/S (Platinum-Rhodium): High-temperature applications (up to
1600°C).
Type N (Nicrosil-Nisil): High stability and resistance to
oxidation.
Applications:
Temperature measurement in industrial processes, furnaces, engines,
and laboratories.
Often paired with MI Cable for protection in harsh environments.
MI Cable and Thermocouple Combination
MI Cable is often used as the protective sheath for thermocouples,
especially in high-temperature, high-pressure, or corrosive
environments.
The combination provides:
Enhanced durability and longevity of the thermocouple.
Accurate temperature measurement in extreme conditions.
Protection against mechanical damage and environmental factors.
Applications :
- Solid waste incinerators
- Sintering powdered metals
- Firing ceramic materials
- Gas or oil fired furnaces
- Fuel fired heat exchangers
- Box furnaces
- Nuclear or hydrocarbon based energy plants
- And many more...

Key Considerations When Using MI Cable with Thermocouples
Sheath Material: Choose a sheath material compatible with the
environment (e.g., stainless steel for general use, Inconel for
high temperatures).
Insulation Resistance: Ensure proper insulation resistance to avoid
signal leakage.
Flexibility: MI Cable can be rigid or flexible, depending on the
application.
Termination: Proper termination and sealing are critical to prevent
moisture ingress.
Calibration: Thermocouples should be calibrated regularly for
accurate measurements.
