Thermocouple

 



A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor.

Type   Range Comments
B + 70%Platinum+30%Rhodium 0~1700℃ Oxidizing or Inert; High Temperature.
