The Mechanism of the Occurrence of Acquired Thermoelectric Inhomogeneity of Thermocouples and its Effect on the Result of Temperature Measurement

  • THERMAL MEASUREMENTS
  • Published:
Measurement Techniques Aims and scope

The occurrence of an error due to the thermoelectric inhomogeneity of thermocouple electrodes, acquired during prolonged use, is considered, and the properties of this error are formulated. A mathematical model of the error of chromel and alumel electrodes is constructed, the error in measuring the temperature is estimated, and the most dangerous mode of operation of the thermocouples is revealed.
