FBG Strain Sensor
Fiber Bragg gratings are very sensitive to stress and temperature. No matter whether the FBG is subjected to stress or the ambient temperature changes, it is reflected in the fiber grating that the grating pitch has changed, that is, the fiber grating sensor has corresponding strain. This means that when you want to use FBG fiber strain sensorfor accurate testing, you must consider whether the ambient temperature has changed, you must deduct the effect of temperature on the reflected wavelength from formula Strain(μɛ)=((λS-λS0）-（λT-λT0）*KT)/Ks, that is to say, let (λT-λT0)=0 or the value of (λT-λT0) is numerically known, this process is called FBG Temperature Compensation for Strain sensors.
Types of FBG Strain Sensor

FBG Strain Sensor MST-01
FBG Strain Sensor MST-01
Mountable Strain Sensor MST-01 adopt the technology of temperature compensation, two FBG inside the housing, which can eliminate the influence of the temperature from strain monitoring.
FBG Strain Sensor EST-01
FBG Strain Sensor EST-01
Embedded Strain Sensor EST-01 adopt the technology of temperature compensation, with the characteristics of anti-electromagnetic interference, anti-lightning, no electricity detection, it is suitable for strain monitoring in harsh environments.
Principle and Method of Temperature Compensation for FBG Fiber Optic Sensor
The best way for AtGrating to compensate the temperature for the FBG strain sensor is to inscribe double gratings in one fiber, and then package it into the FBG strain sensor with temperature compensation, one FBG is used to measure the strain, and the other is used to measure the strain. Since the strain FBG and temperature FBG are in the same temperature environment, the temperature value measured by temperature FBG can be regarded as the temperature of strain FBG. Hence we can deduct the influence of temperature on the reflected wavelength from formula Strain(μɛ)=((λS -λS0)-(λT-λT0)*KT)/Ks, so as to obtain an accurate strain change value.
