Easy to forget the platinum-rhodium thermocouple details

For platinum rhodium thermocouple, he still common temperature parts, he can be used for the temperature of 1600 degrees, if he is in a relatively short time can also be used in the temperature of 1800 degrees. His thermoelectricity is very good, oxidation resistance is good too. Usually, we will have the staff to check on him, but there are still some problems will be forgotten.

of course HuiXin thermal meter platinum-rhodium thermocouple he accidentally wire clean degree is very important, if platinum-rhodium thermocouple wire pair were contaminated, or oxidation, that have a black silk surface. The accuracy of this time he will finally. Followed by platinum rhodium thermocouple his length, we also look at thermocouple in he left temperature measuring the width of the place is enough. Actually mentioned in metal thermocouple check rules, the length of the thermocouple he is no less than 750 mm, because it would be negative if the length of the thermocouple him enough, the error of the shorter then he the greater the error.

the degree of curvature of platinum rhodium thermocouple wire pair he is also easy to be ignored, because he not only thin but also accidentally silk is soft, so it is easy to occur deformation. If he deformation after platinum-rhodium thermocouple thermoelectric property will have influence the result of the test. So every time we check all pay more attention to the dual silk.
