Problems solved by technology

However, since the measurement distance will vary with the aperture of each brand, the measurement distance will also be different. Therefore, the design of the extension tube 14 in this technology needs to be designed in accordance with different lengths and dimensions, which increases the design complexity. Complexity
In addition, the tight integration of the outer wall of the furnace, the extension pipe and the thermometer will also increase the difficulty of design

Abstract

The invention relates to a radiation standard device with a mechanism preventing heat convection, mainly comprising a black furnace and a pressure adjusting unit. The black furnace has a furnace hole, the pressure adjusting unit being connected with the black furnace. The pressure adjusting unit adjusts press of an opening of the furnace hole according to temperature difference of external environment. The invention blocks heat convection between the furnace of the black radiation source and the external environment by controlling pressure change at the opening of the pressure adjusting unit, further providing a stable radiation standard source for correction and test service.

Description

technical field [0001] The invention relates to a radiation standard device, in particular to a radiation standard device with a heat convection prevention mechanism which utilizes changes in air pressure to prevent heat convection from occurring. Background technique [0002] Due to the vigorous development of non-contact temperature measurement, various types of products such as infrared thermal imaging cameras and radiation thermometers are constantly being introduced to bring convenience without safety concerns to the world. It is also one of the fastest growing industries in recent years. As long as the object is above absolute zero, it will emit heat radiation, so how to measure the correct temperature with non-contact temperature, and use it as an effective judgment factor, and meet the standard requirements, is an important issue to improve product quality. [0003] At present, non-contact infrared thermal imaging cameras, radiation thermometers, and even ear thermom...
