The treatment method for the temperature difference of the vacuum dryer: the reading value of the instrument panel of the vacuum drying equipment is different from the reading value of the glass rod thermometer in the vacuum chamber: under normal circumstances, the electric heating vacuum dryer uses the first heating type wall, and then according to The way the radiant source towards the wall heats the steel; that way, the thermostat temperature sensor can be mounted on the outer wall, and the controller can accept the heat convection, transmission and radiation sources together.
On the other hand, the glass rod thermometer in the vacuum chamber only accepts thermal radiation, because the blackness of the glass rod is unlikely to exceed, so most of the thermal radiation is refracted, so the temperature of the reflecting surface of the glass rod thermometer must be lower than that of the equipment. temperature reading.
Normally, 150°C is all right when the instrument reading differs from the glass rod thermometer reading at 30°C. 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 can be moderately reduced, but it cannot be cleared, and the reliability of the sealing type is improved. probability of reliability. If you don't want to see the difference from a specific point of view, please use the temperature controller's unique display information effect to deal with it.
