Numerical Research of the Measurement Error of Temperature Thermocouples with the Isolated Seal
1 National Research Tomsk Polytechnic University, 634050 Tomsk, Russia
Mathematical models of heattransfer are developed for an assessment of measurement errors of temperature by thermocouples with an isolated and uninsulated seal. Dependences of necessary time of heating (for authentic measurement) for the thermocouples with an isolated seal manufactured of different materials are set. It is shown that for thermocouples with isolated seal minimum necessary duration of heating up slightly exceeds this index for thermocouples with an uninsulated seal.
