摘要
文章针对SBE 3海水温度传感器存在的停振现象,通过重复实验和排除实验进行了系统地测量研究,发现停振时间间隔远大于传感器所标定的时间常数,极大地影响了海洋测量结果的准确性。重复实验和排除实验的数据分析结果表明,SBE 3系列海水温度传感器的停振时间间隔与传感器的运动速度无关,而与温度阶跃呈线性关系,温度阶跃越大,停振时间就越长,且不同传感器的停振时间间隔与温度阶跃的线性关系基本一致。SBE 3海水温度传感器的停振现象是传感器自身产生的,与测试设备的F/V模块无关。
Aimed at the oscillator death of SBE 3 marine temperature sensor,a systematic measurement study was carried out by repeated experiments and exclusion experiments in this paper.It has been discovered that the interval time of oscillator death was much bigger than the calibrated time constant of sensors,which greatly influenced the accuracy of marine survey results.The results of repeated experiment and exclusion experiment data analysis show that the oscillator death time interval of SBE 3 marine temperature sensor has nothing to do with the motion speed of the sensor,which is linearly related to the temperature gradient.The larger the temperature gradient is,the longer the oscillator death time will be.The linear relationship between oscillator death time interval of different sensors and the temperature gradient is basically consistent.The oscillator death phenomenon of SBE 3 marine temperature sensor is generated by the sensor itself,which has nothing to do with the F/V module of the test equipment.
