Диапазон температур фемтосекундного волоконно-оптического датчика температуры на основе решетки Брэгга — Диапазон температур: Высокая термостойкость до 600°C, Низкая термостойкость до -200°C — Термометр FBG
This article introduces the operating Диапазон температур OFSCN® 500°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer), including its maximum high-temperature and low-temperature resistance values. It also discusses the determination method and principles of the operating temperature range of fiber Bragg grating temperature sensors, including the stainless steel material and femtosecond fiber bragg grating used.
Диапазон рабочих температур датчиков на волоконных брэгговских решетках в основном определяется самой волоконной брэгговской решеткой и упаковочным материалом датчика. Поэтому анализ следует проводить с этих двух аспектов.
1. Рабочий Диапазон температур Упаковочный материал для OFSCN® 500°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer)
The OFSCN® 500°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer) by DCYS adopts a unique patented packaging technology using seamless stainless steel tubes. The structure is minimalist, without adhesives or Другое auxiliary materials, consisting only of fiber bragg gratings (FBG) and stainless steel seamless tubes. Therefore, the determination of its operating range only requires analysis of the fiber bragg grating (FBG) and stainless steel materials.

For the OFSCN® 500°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer), the working temperature range in the low-temperature region at the measurement point is -200°C, and in the high-temperature region, it has a long-term Диапазон рабочих температур +350°C and a short-term Диапазон рабочих температур +550°C. In practical measurements, customers have achieved temperatures of up to +600°C within shorter periods.
2. Диапазон рабочих температур Фемтосекундная FBG для OFSCN® 500-degree Celsius Capillary Seamless Steel Tube Femtosecond FBG Temperature Sensor (FBG Thermometer)
В данной модели продукта используется волокно с допированным полиимидным покрытием, и долговременная рабочая температура полиимидного волокна обычно составляет около +500°C, а кратковременный диапазон рабочих температур может достигать +600°C.
The OFSCN® 500°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer) internally encapsulates femtosecond laser-written fiber bragg gratings (Femtosecond FBG). Due to the use of doped polyimide fiber, the FBG will degrade above 600°C. In this configuration, the stainless steel's temperature resistance is not the limiting factor; it is the degradation temperature characteristic of the femtosecond laser-written fiber bragg grating (Femtosecond FBG) that becomes the limitation.

Based on final testing, the OFSCN® 500°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer) has a low-temperature Диапазон рабочих температур -200°C, a long-term high-temperature Диапазон рабочих температур +500°C, and a short-term high-temperature Диапазон рабочих температур +600°C. It can be repeatedly used at temperatures up to +600°C (continuous usage in a +500°C environment). It should be further clarified that the high-temperature range is based on actual measurements, while the low-temperature range is theoretical.
