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® 100°C Capillary Seamless Steel Tube Fiber Bragg Grating (FBG) temperature sensor (FBG thermometer), including its maximum high-temperature endurance 및 maximum low-temperature values. It also describes the methods 및 principles for determining the working temperature range of fiber bragg grating temperature sensors (including the stainless steel materials used 및 the FBG written using ultraviolet lithography).

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

1.  Working Temperature Range of Packaging Material for OFSCN® 100-degree Celsius Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer)

The OFSCN® 100°C Capillary Seamless Steel Tube Fiber Bragg Grating (FBG) temperature sensor developed by DCYS adopts a unique patented technology for stainless steel seamless tube packaging. Its structure is extremely simple, with no adhesive or 기타 auxiliary materials. It is composed of only fiber bragg gratings (FBGs) and stainless steel seamless tubes. Therefore, determining its operating range only requires analyzing the fiber bragg gratings (FBGs) and stainless steel materials.

For the OFSCN® 100°C Capillary Seamless Steel Tube Fiber Bragg Grating (FBG) temperature sensor, its long-term working temperature range is from -40°C to +100°C, 및 its short-term working temperature range is from -60°C to +120°C. Both of these temperature ranges are far below the temperature limits of the stainless steel material. Therefore, this temperature range is mainly determined by the coating material, polyacrylate, used on the fiber bragg grating (FBG).

전통적인 통신 산업에서 고품질 광섬유를 사용하는 경우, 폴리아크릴레이트 코팅 광섬유의 온도 범위는 일반적으로 -40°C에서 +85°C입니다.

The OFSCN® 100°C Capillary Seamless Steel Tube Fiber Bragg Grating (FBG) temperature sensor uses Corning SMF-28e fiber, 및 its long-term working temperature range is determined to be from -40°C to +100°C, with a short-term working temperature range from -60°C to +120°C. It can be repeatedly used at temperatures up to +120°C (continuous use in a +100°C environment). It should be noted that the above temperature ranges provide measured values for the high-temperature portion 및 theoretical values (not reaching the limits) for the low-temperature portion.
