The heating elements of the vacuum furnace temperature tester are generally arranged in a circle, the vacuum furnace is relatively common. Its heat transfer mode is only radiation, conduction convection.
The following is a brief introduction to the principle of temperature uniformity measurement of vacuum furnace by the manufacturer of furnace temperature tester. Generally, there are three aspects as follows:
(1) When removing the cover for temperature measurement, the flange with 9 holes is installed, the flange enters the furnace chamber to measure the thermocouple is fixed on the bracket. Install the measuring thermocouple sealing washer, rubber washer vacuum grease sealing bolt to compress prevent leakage.
(2) The temperature uniformity of the vacuum furnace in the temperature control system of the heating tester controls the heating temperature, heating current measurement recording. With thermocouple temperature switch uniformity measuring instrument, measuring thermocouple temperature measuring instrument, measuring range of 0 ~ 1300 ℃, SR93 digital thermometer of Japan island, compensation wire.
(3) According to the requirements of the standard, the measurement of the furnace temperature of the vacuum furnace adopts the method of 9 points measurement in the effective heating area. 9 points are arranged in the effective working space of 600mm × 600mm × 900mm. There are 3 thermocouples in any plane.
According to its working principle, we can operate it effectively. I hope it can help you.
