black body furnace annually
Infrared pyometers shall be calidrated to a black body furnace annually,红外线高温计应使用一个黑体炉每年校准一次。这个黑体炉是什么东西？是翻译成黑体炉吗？ 这么没有人回答:'( 本帖最后由 wty728 于 2010-5-28 17:01 编辑Blackbody Calibration Source Truths
A precision blackbody (black body) is a controlled source of thermal radiation used to calibrate infrared radiation thermometers (pyrometers), thermal imagers and radiation heat flux gauges and radiometers. They are highly specialized and have been described and developed since Max Planck invented the concept at the end of the 19th century.
Needless to say, a practical blackbody simulates Planck's ideal source and the closeness of that simulation to the ideal, the more expensive they are. So, selection of one is a careful exercise in tradeoffs of needs versus cost. One, of course, must know what they need before selecting a given unit.
Blackbody thermal radiation sources are not something purchased every day, yet they are often kept for years. Some are used infrequently. Some are used with surprising regularity. So, a blackbody purchase is done usually with great care. On the connecting pages and links we have put together a few more helpful truths about them and some key specification components that must be considered.
