The sensitivity of the FBG temperature sensor is sometimes referred to as the resolution or temperature sensitivity of the sensor, that is, the minimum temperature change that the sensor can measure.
To be precise, the sensitivity of each FBG fiber optic sensor temperature is different, mainly ***ermined by the reflection wavelength of the FBG and the natural characteristics of the glass filament used in the fiber, and sometimes it is also related to the sensor packaging method. The method can sensitize or desensitize the FBG.
Types of FBG Temperature Sensor
FBG Temperature Sensor CT-01
Ceramic housed fiber optic temperature transmitter CT-01, high temperature and electric power resistance, makes it perfectly suitable for the temperature sensing in power station, oil & gas industries.

FBG Temperature Sensor ST-01
Stainless Steel tube housed temperature sensor ST-01, waterproof, commonly used in long-time harsh environmental temperature sensing in railway, bridge, dam, tunnel, etc.

Working Principle of FBG Temperature Sensor
Figure below shows a schematic diagram of a fiber core with a Fiber Bragg Grating (FBG) inscribed (the fiber core diameter is 9 microns). People use UV phase mask irradiation, Femtosecond laser point-by-point writing or other processing methods to form countless weakly reflective surfaces with the same ***cing in the core part of the fiber, these weakly reflective surfaces are called fiber gratings, and the distance between each weakly reflective surface is called the grating pitch or grating period (we generally use the symbol ¦« to denote it - remember this symbol, we will need it later).
The basic sensing measurement can be carried out using the above-mentioned fiber bragg grating, and its principle is shown in Figure below:
Shown in the above, the broadband incident light enters the fiber from one end of the grating sensor, and encounters the fiber bragg grating (FBG), most of the wavelength of light directly passes through the FBG as transmitted light. |
