SZC15-4型多参数剖面仪设计

CTD是测量海水温度、电导率和压力的仪器,在海洋科学考察、海洋资源调查开发、海洋环境监测预报和海洋军事研究中应用广泛。SZC15-4型多参数CTD是国产SZC15系列CTD最新型号,用于测量海水的温度、电导率、深度和叶绿素浓度,适用于近岸海洋调查。文中介绍了SZC15-4型多参数CTD剖面仪的性能、工作原理、系统组成和工作流程。并通过海上试验,与SBE19CTD在相同环境条件、相同采样速率下作比测,通过对实验数据做相关运算得出SZC15-4型CTD与SBE19在温度、盐度相关性优于0.999 9,表明两种仪器具有很高的相关特性。

Design of the SZC15-4 Multi-Parameter Profiling Instrument

CTD is a kind of instrument used to measure seawater temperature, conductivity and pressure, and is widely applied in marine scientific exploration, marine resource survey and exploitation, marine environment monitoring and forecast, and marine military research. The SZC15-4 multi-parameter CTD is the newest type of the SZC15 series for measuring temperature, conductivity, depth and chlorophyll concentration, suited to offshore marine survey. This paper introduces the function, operational principle, system composition and work flow. During the sea trial, the SZC15-4 and SBE19 CTDs are tested and compared under the same environmental condition and sampling rate. Through the correlation calculation with experimental data, it is concluded that the correlations of temperature and conductivity between SCZ15-4 and SBE19 CTDs are over 0.9999, indicating that the two kinds of instruments have high similarity.
