Thermocouple

Thermocouple

A Thermocouple is a Temperature Measurement Sensor consisting of 2 different specially selected metal wires. The wires 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 - 9 different types or Calibrations are commonly used although at least 8 other types are known for very specific capabilities or applications.
  • Temperature measurement range rom Sub-zero to over 4,000 degrees F
