Thermocouples are voltage devices that indicate temperature measuring with a change in voltage. A Thermocouple is a component made of two different metals connected with each other at one end. An electrical potential (thermoelectric force) is caused due to the Seebeck effect at the open end if the connection and free ends are exposed to different temperatures brazilian hair bundles.
Often the thermocouple is located inside a metal or ceramic shield that protects it from exposure to a variety of environments. Metal-sheathed thermocouples also are available with many types of outer coatings, such as Teflon, for trouble-free use in acids and strong caustic solutions.
Thermocouples are suitable for temperature measurement in the range of 0 °C to +1800 °C. They stand out due to the fast response time and high vibration resistance. Please refer thermocouples reference tables (see IEC 60584)
Thermocouples measure voltage change and signify temperature.
