Water-cooled temperature measurer for high-temperature, high-vacuum and high-volatile matters

Abstract

The invention relates to a water-cooled temperature measurer for high-temperature, high-vacuum and high-volatile matters, which comprises an infrared temperature measuring instrument (10), temperature measuring glass (7) and a cold filtering and decontaminating device (5). The temperature measuring glass (7) is located between the infrared temperature measuring instrument (10) and a cavity (1) mounted on equipment for holding the high-temperature, high-vacuum and high-volatile matters, the temperature of the cold filtering and decontaminating device (5) is lower than that of the high-temperature, high-vacuum and high-volatile matters in the cavity (1), the cold filtering and decontaminating device (5) is arranged between the cavity (1) and the temperature measuring glass (7), and the surface of the temperature measuring glass (7) is communicated with the cavity (1) via the cold filtering and decontaminating device (5). The water-cooled temperature measurer for the high-temperature, high-vacuum and high-volatile matters can continuously reduce sedimentation velocity of the volatile matters in the equipment on the temperature measuring glass.

Description

technical field [0001] The invention relates to a high-temperature, high-vacuum, high-volatile matter water-cooled temperature measuring device. Background technique [0002] The temperature monitoring technology of containers operating under high temperature, high vacuum and high volatiles is currently divided into contact temperature measurement and non-contact temperature measurement, and non-contact temperature measurement is divided into many types, and the infrared temperature measurement is based on its response The advantages of fast time, high accuracy, safe use and long service life are widely used. [0003] Molecules inside any object whose temperature is higher than absolute zero are constantly moving, and this molecular motion will cause the object to continuously emit infrared radiation energy to the surrounding space, thus forming a certain temperature field on the surface of the object. If the infrared radiation energy emitted by the object to the surroundin...

Problems solved by technology

[0005] In the existing technology, adding a water-cooled switching valve device to the temperature measuring device can effectively slow down the deposition rate of volatiles inside the equipment on the temperature measuring glass, but since the valve must be open when the thermometer measures the temperature, At this time, the deposition speed of volatiles on the temperature measuring glass is accelerated, which affects the accuracy of the measurement data of the thermometer and cannot effectively control the system
