Uncertainty of temperature measurement by thermocouple is analyzed
at same time
the uncertainty of stability and uniformity of temperature measurement are analyzed as well.The analysis brings forward the theoretical support for the parameters measurement and control of temperature field under precise environment.It shows the uncertainty of temperature measurement is closely related to the measurement uncertainty of both thermocouple EMF and the sensor temperature at reference-side.The measurement uncertaint...
