Рисунок 6 shows the measured graph of the calibration coefficient (calibration function) of an actual sold OFSCN® 300°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor (FBG Thermometer). This curve displays the corresponding relationship between the sensor's wavelength variation and temperature change. The calibration range is from room temperature to 300°C, with a calibration temperature interval of approximately 20°C.
В отличие от легенды, в официальном заводском отчете мы также предоставляем конкретные значения длины волны и температуры. Для общих измерений температуры этот калибровочный коэффициент может быть использован напрямую.
Each OFSCN® 300°C Capillary Seamless Steel Tube Fiber Bragg Grating Temperature Sensor has a unique calibration coefficient (calibration function), which is tested и determined by the Quality Inspection Department of DCYS. It is recorded on the company's official website for customers to query 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!'
