광섬유 브래그 격자 감지 기술 백과사전 - FBG FAQ - FBG 센서 FAQ - FBG 복조기 FAQ - FBG 일반 응용 문제 분석

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 및 low-temperature resistance. It also discusses the methods 및 principles used to determine the working temperature range of fiber bragg grating temperature sensors, including the stainless steel material 및 femtosecond fiber bragg grating used.

광섬유 브래그 격자 센서의 작동 온도 범위는 주로 광섬유 브래그 격자(FBG)와 센서 패키징 재료에 의해 결정됩니다. 따라서 이 두 가지 측면에서 분석이 필요합니다.

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 기타 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, 및 in the high-temperature region, it is up to +800 degrees Celsius, with short-term tolerance up to +1000 degrees Celsius.

2. 작동 온도 범위 펨토초 FBG용 OFSCN® 800-degree Celsius Capillary Seamless Steel Tube Femtosecond FBG Temperature Sensor (FBG Thermometer)

이 모델에 사용된 광섬유 브래그 격자는 펨토초 레이저 점대점 기록(Femtosecond FBG) 방식으로 제작되었으며, 1000도까지의 온도에서도 손상 없이 견딜 수 있습니다. 가장 바깥쪽 패키징 재료는 1000도까지의 온도를 견딜 수 있는 특수 고온 저항 합금입니다.

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 및 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.
