For sleeve thermometers, there is a deviation of about 1°C each time they are inserted and recalibrated. How can this be resolved? Every time, the calculated cost is still too high
Is there an issue with the insertion depth of the temperature sleeve? Generally at 2/3 of the pipe length
Which standard does this data follow?
1℃ is completely normal – how precise control is required here! Such requirements raise the issue to a different level regarding instruments; regular discussions are of little use in this case
What is the temperature measurement range? A difference of 1°C within the range of 0~1000°C is clearly different from a difference of 1°C within the range of 0~100°C; the precision for the former is 0.1, while that for the latter is 1 ； What is the condition of the site? Is there any electromagnetic interference? What is the ambient temperature? All of these will affect the readings ； Due to the additional sleeve, how is the condition of the sleeve? For example, the time constants of steel sleeves and ceramic sleeves differ significantly; will the readings be stable during on-site testing?
