Abstract

PURPOSE: To measure the surface temperature of piping or apparatus as the material to be heat-insulated with a contact type temperature measuring structure with good accuracy by providing a convection preventing cover covering the end of thermocouple.
CONSTITUTION: A thermocouple 11 and the narrow temperature measuring part gas space 23 including the surface 19 to be temperature-measured in contact with this thermocouple are enclosed with a convection-preventing cover 22 and the convection-preventing cover 22 is held pressed to the surface 19 to be temperature- measured by a convection-preventing cover pressure spring 21, whereby the isolation from surrounding gas space 18 is assured. The gas in the temperature measuring part gas space 23 stagnates and its temperature is determined from the balance between the heat input from the surface 19 to be temperature-measured and the heat dissipotion from the convection-preventing cover 22 to the surrounding gas space 18 and positively becomes nearly uniform at the value close to the temperature of the surface 19 to be temperature-measured as compared to the temperature of the surrounding gas space 18
