Research On The Key Technology Of ST3000Pressure Transmitter

Pressure transmitter as industrial measurement instrument, plays a very important rolein the industrial automation control. With the industrial automation degree is more andmore higher, we need to constantly improve the performance of pressure transmitter. Dueto the current overall level of China’s development of the transmitter is evidently lowerthan abroad. Restricted mainly by technology and enterprise competence. How to increaseour strength, the shortest way is the introduction of digestion and absorption of foreignadvanced technology.In view of our independent product demand, this article mainly researches the sensorof the ST3000pressure transmitter measurement and the senser of the welding technology.In the Structural components of the senser, we just research the key of the centerdiaphragm for the how to choose material, how to design the waveform，and how todevelopment the heat treactment of the center diaphragm. Establishment of the mainfactors for effect rigidity of the center diaphragm. For the welding technology of sensorjust research the electron beam welding technology and rolling welding technology.Establishment how to select the fitness welding technology in the sensor welding. Andhow to set parameter of the electron beam welding and rolling welding. Finally, abovethose research, And provide the theoretical support for our new design of pressuretransmitter.
