海洋温度传感器动态温度测量误差及修正方法研究OA

To improve the measurement performance of domestic ocean temperature thermometers,a study on dynamic temperature measurement errors and correction methods was conducted based on a self-developed ocean temperature sensor.Stability testing and precise static water bath calibration of the self-developed thermometer were carried out,achieving an expanded uncertainty of 0.93 mK(k=2).A large high-stability thermostatic bath was utilized to simulate actual sea trial environments,and dynamic temperature measurement experiments were conducted at 5℃and 35℃.The results indicate that during the sensor's deployment,temperature changes in the measuring circuit caused a deviation between the measured temperature and the true temperature,with the maximum deviation reaching approximately 0.40 mK.By applying temperature compensation to the measuring circuit,the stability of the temperature measurement was effectively improved.The research findings provide technical references for the development of high-precision domestic ocean temperature thermometers.
