Энциклопедия технологии волоконно-оптических брэгговских решеток - FBG FAQ - FBG Датчик FAQ - FBG Демодулятор FAQ - Анализ общих проблем применения FBG

This article introduces the working temperature range of the OFSCN® 800-degree Celsius capillary seamless steel tube fiber bragg grating temperature sensor (FBG thermometer), including the values for its maximum high-temperature и low-temperature resistance. It also discusses the methods и principles used to determine the working temperature range of fiber bragg grating temperature sensors, including the stainless steel material и femtosecond fiber bragg grating used.

Рабочий диапазон температур волоконно-оптических датчиков Брэгга в основном определяется волоконно-оптической брэгговской решеткой (FBG) и материалом корпуса датчика. Поэтому необходимо провести анализ с этих двух сторон.

1.  Working Temperature Range of Packaging Material for OFSCN® 800-degree Celsius Capillary Seamless Steel Tube Femtosecond Fiber Bragg Grating Temperature Sensor (FBG Thermometer)

The OFSCN® 800-degree Celsius capillary seamless steel tube fiber bragg grating temperature sensor (FBG thermometer) developed by DCYS adopts a unique stainless steel seamless tube patent packaging technology. It has a simple structure with no glue or Другое auxiliary materials. The sensor consists only of the fiber bragg grating (FBG) and the stainless steel seamless tube. Therefore, the working range can be determined by analyzing these two materials.

For the OFSCN® 800-degree Celsius capillary seamless steel tube fiber bragg grating temperature sensor (FBG probe), the working temperature range in the low-temperature region is -269 degrees Celsius, и in the high-temperature region, it is up to +800 degrees Celsius, with short-term tolerance up to +1000 degrees Celsius.

2. Рабочий диапазон температур Фемтосекундный FBG для OFSCN® 800-degree Celsius Capillary Seamless Steel Tube Femtosecond FBG Temperature Sensor (FBG Thermometer)

Волоконная брэгговская решетка, используемая в этой модели, изготовлена с использованием пошаговой записи фемтосекундным лазером (фемтосекундный FBG) и может выдерживать температуры до 1000 градусов Цельсия без деградации. Внешний упаковочный материал представляет собой специальный высокотемпературный сплав, способный выдерживать температуры до 1000 градусов Цельсия.

After testing, the OFSCN® 800-degree Celsius capillary seamless steel tube fiber bragg grating temperature sensor exhibits a working temperature range of -269 degrees Celsius in the low-temperature region и up to +800 degrees Celsius in the high-temperature region, with the ability to reach +1000 degrees Celsius in shorter durations. It should be noted that the high-temperature range is based on measured values, while the low-temperature range is based on theoretical values.
