Thermocouple
A Thermocouple is one of the most utilized temperature sensor measurement technologies used throughout science, industry and research. They are also utilized in commercial and consumer applications with food processing, indoor heating and cooling
Thermocouples can provide a temperature range of -454°F to 4,200°F (-270 to 2315°C) along with a great diversity of choices with Response Time and Durability. Small (Mirco) designs with Very Fast 0.25 seconds response to Large (Rugged) constructions design for more gradual measurements.
Other attributes include ease of use and fairly good accuracy of 1 to 4°F (0.5 to 2°C) depending on the design and temperatures being measured.
The base technology of thermocouples is 2 different specially selected metal alloys (commonly wire or thin strip construction) joined together at the tip creating a junction (thermo - coupling). 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.
