Thermocouple

Thermocouple

A Thermocouple is one of the most widely utilized Temperature Measurement Sensor Technologies throughout science, industry and research. This distinction is due to the diverse capabilities of the base design itself. For example thermocouples have a very wide temperature range of -454°F to 4,200°F (-270 to 2315°C). A great versatility of diameter and durability ranging from very small fast response (Micro) design to large (Rugged) constructions. Other attributes include ease of use and fairly good accuracy of 1 to 2 degrees depending on the design and temperatures being measured.

Thermocouples consist of 2 different specially selected metal alloys, commonly referred as Calibrations. The wires or flat strips are joined together at one end to create a junction (electrical connection). A change in temperature at this junction results in the wires creating a very small voltage (millivolt) signal. The voltage is measured and compared to specific temperatures and type of thermocouple types utilized.   

  • Thermocouple Types or Calibration - 9 Different types (J, K, T, E, R, S, B, C and N) are the most utilized design, although at least 8 other types are available for very specific capabilities or applications. Such as extreme temperature tungsten rhenium alloys (D and G) or Type P (Plantinel II to mimic type K at higher temperature with enhanced corrosion resistance) along with other combinations made with Gold, Platinum, Iridium, Rhodium and other Nobel metal combinations
  • Temperature measurement range from Sub-Zero -454°F (-270°F) to extreme High temperatures of 4,200°F (2315°C)
  • Diameters range from Very Fine .003" (40 gage) with fast response to Large .128" (8 gage) very durable are commonly used, although smaller and larger diameters or thickness are utilized in specific applications.
