How to deal with the temperature difference of the dryer: the reason why the reading value of the instrument panel of the vacuum drying equipment is not the same as that of the glass rod thermometer in the vacuum chamber: generally, the electric heating vacuum dryer selects the heating wall first, and then according to the way of heating the steel parts by the radiation source facing the wall; In this way, the temperature sensor of the temperature controller can be installed on the external wall of the building, and the controller can receive the heat convection, transmission and radiation source together.
On the other hand, the glass rod thermometer in the vacuum chamber can only accept thermal radiation, because the blackness of the glass rod is unlikely to exceed, so most of the thermal radiation is refraction angle, so the temperature of the reflecting surface of the glass rod thermometer must be less than the temperature reading value of the instrument.
通常情況下,當儀器設備讀值與玻璃棒溫度表讀值在30℃時不同時,150℃是一切正常的。
Under normal circumstances, when the reading value of the instrument is different from that of the glass rod thermometer at 30 ℃, everything is normal at 150 ℃.
If the temperature sensor of the temperature controller is installed in the type, the difference between the temperature value of the glass rod thermometer and the temperature reading value of the instrument and equipment can be moderately reduced, but it can not be cleared. The credibility of the sealed type increases the probability of unreliability. If you don't want to see the difference from a specific perspective, please use the distinctive display information effect of temperature controller to deal with it.
