The temperature sensitivity of an all-fiber temperature sensor created using the melting effect is investigated. In order to study the dependence, a special model was developed and assembled to check the sensitivity of the sensors to temperature changes. During the experiments, the temperature dependences of the spectral shift for the sensor were obtained in the 30–90°С and 20–320°С temperature ranges. During the study, a graph of the dependence of the spectrum on temperature was obtained and a calibration graph was constructed. Thus, the temperature sensitivity of the sensor was determined, which was ≈16 mln^–1/°C. The results of the fiber strength in an acrylate coating were obtained before and after tests using the axial tension method. It was found that the ultimate strength of the fiber decreased by more than 2 times when exposed to high temperature.

利用熔化效应创建的全光纤温度传感器的特性研究

研究了利用熔化效应创建的全光纤温度传感器的温度敏感性。为了研究这种依赖性，开发并组装了一个特殊模型来检查传感器对温度变化的敏感性。在实验过程中，在30–90°С和20–320°С温度范围内获得了传感器光谱偏移的温度依赖性。在研究过程中，获得了光谱与温度的关系图，并建立了校正图。因此，确定了传感器的温度灵敏度，约为1600万^–1/℃。在丙烯酸​​酯涂层中的纤维强度的结果是在使用轴向张力方法测试之前和之后获得的。发现当暴露于高温时，纤维的极限强度降低了两倍以上。
