Product Overview
A thermocouple temperature probe uses the thermoelectric effect to
measure temperature through two different metal wires joined at one
end, generating a voltage corresponding to temperature differences.
Construction
- Wires: Made of two different conductive metals (copper, nickel,
chromel, alumel)
- Junction: Measuring (hot) junction where wires join, connected to
measuring device (cold junction)
- Insulation: High-temperature resistant materials (ceramic,
fiberglass)
- Sheath: Protective metal or ceramic casing for environmental
protection
Working Principle
Based on the Seebeck Effect: when two different metals are joined
and exposed to temperature gradient, a thermoelectric voltage is
produced at the junction. This voltage relates to the temperature
difference and is converted into temperature readings using
calibration data.
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

Frequently Asked Questions
What are the advantages of using thermocouples?
Wide temperature range, fast response time, simple and rugged
design, relatively inexpensive, suitable for various environments
including extreme conditions.
What are the disadvantages of thermocouples?
Non-linear output requiring calibration, potentially lower accuracy
than other sensors, requires reference junction compensation,
susceptible to electromagnetic interference.
