Thermocouple Cold (Reference) Junction Compensation

Thermocouple cold junction compensation - Beamex white paper

Thermocouples are commonly used temperature sensors in processes. They may seem like very simple simple sensors, but the importance of the cold junction (reference junction) is too often forgotten and this causes error in the measurement.

Read this white paper to learn about:
  • How does a thermocouple work?
  • Types of thermocouples 
  • Thermocouple’s thermovoltage
  • Seebeck coefficients
  • Cold junction compensation methods:
    1. Cold junction in an ice-bath
    2. Cold junction in a known, fixed temperature
    3. Measure the temperature of the cold junction
    4. 4. Automatic on-line compensation in the measuring device
