【Abstract】 In order to meet the continuous measurement application demand of underwater gliders, and to obtain marine hydro-power high-quality cross-sectional data, a new miniaturization, low-power-consumption, light-weight SZQ1-1 CTD sensor has been designed in this paper for underwater gliders. The CTD has used the electromagnetic induction type principle to measure conductivity, integrated fast-responsed thermistor and pressure sensor, and is controlled by PIC18 F2520 microcontroller in the circuit. The CTD measuring instrument has been calibrated many times in the laboratory, and the data quality is proved to meet the requirements of sea test. In October 2016, the CTD sensor was compared with SBE19 Plus of Seabird in the Jiaozhou Bay, Qingdao.Sea test results show that the the measurement results of CTD sensor are similar to those from the SBE19 Plus,and the accuracy of temperature, salt and depth profile data obtained in a real-time manner meets the requirements of the underwater gliders.更多还原
