Thermocouples

Thermocouples are electrical devices used to measure temperature. They consist of two dissimilar metal wires joined at one end, forming a junction. The key features of thermocouples include:

  • Operating principle based on the Seebeck effect, which generates a temperature-dependent voltage
  • Ability to measure a wide range of temperatures, from cryogenic levels to several hundred degrees Celsius
  • Self-powered operation, requiring no external excitation
  • Durability and ability to withstand harsh environments, including heavy vibrations and high pressures
  • Rapid response time to temperature changes
  • Cost-effectiveness compared to other temperature sensors

Thermocouples are widely used in various industries and applications, including:

  • Power generation (monitoring turbines, boilers, and reactors)
  • Metal processing (furnace temperature control)
  • Chemical processing (maintaining reactor temperatures)
  • Food and beverage industry (ensuring proper temperatures in pasteurization and cooking processes)
  • Automotive industry (engine testing and exhaust gas temperature measurement)
  • Aerospace (testing aircraft engines and spacecraft components)
