Platinum rhodium thermocouple what factors influence the accuracy of temperature measurement in the process of production?

Platinum rhodium thermocouple what factors influence the accuracy of temperature measurement in the process of production? Influence, in the process of platinum rhodium thermocouple temperature measurement accuracy has the following five factors:

1. First to see material, that is to say you the thermocouple wire is in accordance with the proportion of the composition of platinum and rhodium composition, the proportion of normal S type or B type, if the proportion is wrong, that is to say you accidentally wire must have a problem, and certainly not accurate temperature measurement.

2。 Thermocouple wire welding is correct, the effect of welding will be like small ball, there can be no gap, or it will affect the temperature measurement;

3。 Choose whether reasonable operation in the process of protecting tube;

4。 Installation is reasonable right;

5。 How specific work surroundings.
