741 KG Industrial Furnace Burners Steel Substrate

The general electric heating vacuum drying oven adopts the method of heating the wall surface of the vacuum chamber first, and then performing radiant heating from the wall surface to the workpiece. In this way, the temperature sensor of the temperature control instrument can be arranged on the outside wall of the vacuum chamber. The sensor can simultaneously receive convection, conduction, and radiant heat. The glass rod thermometer in the vacuum chamber can only receive radiant heat, and because the blackness of the glass rod cannot reach 1, a considerable part of the radiant heat is refracted, so the temperature value reflected by the glass rod thermometer is definitely lower than the temperature reading of the instrument . Generally speaking, the difference between the temperature reading of the meter and the reading of the glass rod thermometer within 200 ° C within 30 ° C is normal. If the temperature sensor of the temperature control instrument is arranged in the vacuum chamber, the difference between the temperature value of the glass rod thermometer and the temperature reading of the instrument can be appropriately reduced, but it is impossible to eliminate, and the sealing reliability of the vacuum chamber adds a possibly unreliable link . If you do not want to see this difference from the perspective of practical operation, you can use the unique display correction function of the temperature control instrument to solve
