Foil-like Manganin Sensor Design of Quasi-statical High Pressure Measurement

For the solution of the influence of pressure measurement by crystal deposition,a quasi-statical foil-like manganin sensor for high pressure measurement is designed.Compared with the coil-like manganin sensor,this manganin sensor has the advantage of reliable response and good environmental adaptation.A double-layer cylinder of shrink and autofrettage is used and the computed formula of elastic strength is derivated.A sealed structure of leadthroughs is designed.A pre-bottling liquid medium is determined.An experiment on the manganin sensor characteristics is proceeded.Main statical index is obtained.
