HT—Y—Ⅱ型多模光导纤维测温仪是北京钢铁学院和南京钢铁厂的联合攻关项目。这是一种新型非接触式测温仪表,即在红外线探测器和光学系统中间加一段光导纤维,使探头更接近被测对象,探测器则离开高温区延伸到环境温度比较稳定的地方,不但保证了其测量的准确性,还能避开介质吸收,背景辐射等环境干扰,并能抗电磁干扰。这是继热电偶和红外辐射测温仪之后的又一种新型测温仪。
HT-Y-Ⅱ multimode fiber optic thermometer is a joint research project of Beijing Iron and Steel Institute and Nanjing Iron and Steel Plant. This is a new non-contact temperature measuring instrument, that is, between the infrared detector and the optical system plus a section of optical fiber, the probe closer to the measured object, the detector is left to extend the high temperature to a more stable ambient temperature, not only To ensure the accuracy of its measurement, but also to avoid the media absorption, background radiation and other environmental interference, and anti-electromagnetic interference. This is another new thermometer following thermocouples and infrared radiation thermometers.
