Abstract: The depth simulator can simulate the depth variation of seawater in real time and is an important part of the semi-physical simulation system of underwater equipment. In order to detect the high-pressure resistance and pressure detection accuracy of underwater operation equipment, the deep sea simulator is required to restore the ocean pressure environment as much as possible. This paper proposes a pressure sensing system with a stop device. By integrating the advantages of the large-range pressure sensor, the sensing system has the characteristics of large-range and high-precision. The physical samples were made and tested, and the friction of the sealing ring was found to be too large. Based on the multi-objective optimisation program, Matlab was used to simulate and optimise, and the reasonable structural parameters of the pressure sensing system were obtained.
