【Abstract】 Because of the differences between water and air, there are some differences between pressure measurement in the water and that in the air. Operation principle of one new type of strain sensor that was designed especially to use in under water pressure measurement is introduced,technical difficulties of pressure measurement under water are also solved theoretically,and application examples are given. The result of experiment is satisfactory.更多还原
