Mineral insulated thermocouple cables are specialized cables used for temperature measurement in extreme environments.
A thermocouple temperature probe is a type of temperature sensor that uses the thermoelectric effect to measure temperature. Here’s a detailed overview of thermocouples, their construction, working principle, types, applications, and considerations:
Overview
Definition: A thermocouple temperature probe consists of two different metal wires joined at one end, which generates a voltage that corresponds to temperature differences. This voltage can be measured and converted into a temperature reading.
Construction
Wires: The probe is made of two different conductive metals (commonly copper, nickel, chromel, alumel, etc.) that form a junction.
Junction: The point where the two wires are joined is called the measuring or hot junction. The other end of the wires is connected to a measuring device (cold junction).
Insulation: The wires are often insulated with materials that can withstand high temperatures, such as ceramic or fiberglass, depending on the application.
Sheath: The entire assembly may be encased in a protective sheath made of metal or ceramic, which protects the thermocouple from the environment.
Working Principle
Seebeck Effect: When the two different metals are joined together and exposed to a temperature gradient, a voltage (thermoelectric voltage) is produced at the junction. The magnitude of this voltage relates to the temperature difference between the hot junction and the cold junction.
Measurement: The voltage generated is measured and converted into temperature using calibration data specific to the type of thermocouple.
