Coefficient de température du capteur à réseau de Bragg sur fibre (FBG) femtoseconde - Fonction d'étalonnage d'usine pour thermomètre FBG 800°C, allant de -16 à 806°C et de 524 à 1000°C

The OFSCN® 800°C Capillary Seamless Steel Tube Fiber Bragg Grating temperature sensor (FBG thermometer) , manufactured by DCYS, undergoes temperature calibration before leaving the factory. Along with the product, basic temperature coefficients (also known as calibration coefficients or calibration functions) of the fiber optic grating sensor are provided. The following is a brief description of the temperature calibration of the product at the time of shipment:

I. Product Structure of the OFSCN® 800°C Capillary Femtosecond Fiber Bragg Grating Temperature Sensor

The OFSCN® 800°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG thermometer) adopts a fully metallic packaging method to protect the FBG. The standard product has a diameter of 2.0 millimeters et consists of a three-layer seamless steel tube nested structure. It encapsulates a high-temperature-resistant femtosecond fiber bragg grating (Femtosecond FBG). The overall structure et product are shown in Figure 1, 2, et 3 below:

Figure 6 displays the actual measurement graph of the temperature coefficient (calibration coefficient, calibration function) of a sold OFSCN® 800°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG thermometer). This curve shows the correspondence between the sensor's wavelength variation et temperature change. The test range is from -16 to 806°C, with temperature calibration intervals of approximately 30°C (not strictly enforced).

The OFSCN® 800°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG thermometer) can be temporarily used at higher temperatures (duration of use not tested, repeatability to be determined). Figure 7 presents the actual measurement graph of the temperature coefficient (calibration coefficient, calibration function) of a specific OFSCN® 800°C Capillary Seamless Steel Tube FBG Temperature Sensor (FBG thermometer). This curve shows the correspondence between the sensor's wavelength variation et temperature change. The main test temperature range is from 524 to 1001°C (initial temperature of 53°C), with temperature calibration intervals of approximately 40°C (not strictly enforced).

Contrairement à la légende, dans le rapport d'usine officiel, des valeurs spécifiques de longueur d'onde et de température seront fournies. Pour les mesures de température générales, ce coefficient d'étalonnage peut être utilisé directement.

Each OFSCN® 800°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor has a unique temperature coefficient (calibration coefficient, calibration function). This coefficient (function) is tested et determined by the Quality Inspection Department of DCYS et recorded on the company's official website for customers to check at any time. Based on our experience, the R-square value of the binomial function is generally above 0.9995.

Our philosophy is: 'OFSCN®, make optical fiber stronger!'

  • DCYS is a professional 800°C FBG temperature sensor manufacturer, providing 800°C FBG temperature sensor calibration method, calibration experiment, test report, temperature coefficient, calibration function and Autre information; 800°C fiber bragg grating temperature sensor brand is 'OFSCN'.
