| 摘 要： | 为满足船载拖曳式全光纤海洋温深剖面连续测量的要求,测量海水深度的光纤布拉格光栅(FBG)压力传感器利用FBG温度传感器作为其温补传感器。由于二者对温度同时敏感且对海水温度的响应时间存在不一致性,导致在拖曳测试海水压力时有所偏差。针对这一问题,本文对传感器的温度响应一致性进行分析研究。通过对FBG温度传感器的外管加装绝热材料,使其与FBG压力传感器的温度响应时间接近一致。通过海试验证,FBG压力传感器与标准传感器ALEC(亚力克)具有较高的测量相关性。

| Abstract: | In order to meet the requirements of continuous measurement of ship-borne towed fully fiber optic marine temperature-depth profile,FBG pressure sensor measuring seawater depth uses FBG temperature sensor as its temperature compensation sensor.Because both of them are sensitive to temperature and have different respond time to seawater temperature,there are some deviations in testing seawater pressure.Aiming at this problem,the temperature response consistency of sensors is analyzed.Through installing thermal insulation material for outer tube of FBG temperature sensor,thus,the temperature response time of FBG temperature sensor and pressure sensor is almost consistent.Finally,through the sea trial verification,FBG pressure sensor and standard sensor ALEC have higher measurement consistency. |
