Design of Elastic Cell in Pressure Sensor
The theory of sheet model is used to design the elastic cell of pressure sensor. In this model, the elastic cell shapes like a disk; the ratio of diameter to thickness is in the range from 0.01 to 0.2. According to the calculating result, an elastic cell made by 40CrNiMo with diameter 11mm and thickness 1.6mm can test the pressure form 0 to 100MPa. It is similar with features of calculating result and works well in test.
