HTY-Ⅱ型多模光纤测温仪是采用了多模单丝光纤耦合与传输的先进技术,同时采用了光纤耦合的差动双色式测温原理,因而使仪表降低了漂移,性能稳定可靠。测温仪的探头除采用了直杆可伸缩外,还设计有带反射镜变光路及可弯曲探头。探头可以不用水冷而接近铁水等被测表面,减少了干扰可以实现近距离测量。 HTY-Ⅱ multimode fiber thermometer is a multi-mode monofilament fiber optic coupling and transmission of advanced technology, while using the fiber coupling differential two-color temperature measurement principle, thus reducing the instrument drift, stable and reliable performance. Thermometer probe in addition to the use of the straight rod can be retractable, but also designed with a variable reflector optical path and flexible probe. The probe can be close to the hot metal and other surfaces without water cooling, reducing interference can achieve close-range measurements.
