In order to improve the working ability of magnetic level gauge,a design method of high temperature and high pressure maglev is proposed for magnetic float which affects the performance.Through the analysis of design principles,determine the design sequence.The common float structure was compared,the basic composition was used for finite element analysis and material selection,and the pressure test evaluation was carried out to determine the optimal combination.The parameters affecting the float are determined by theoretical calculation of charging pressure.The laser welding system was built and the floating balls were processed to evaluate the welding process,verify the charging test and verify the mechanical properties of high temperature and high pressure.It solves the problem of working in high temperature,high pressure and low density en-vironment,and broadens the application field of the level meter.
