Bellows refer to tubular elastic sensitive components connected by foldable wrinkled sheets along the folding and stretching direction. Bellows are widely used in instruments and meters、 mainly as measuring elements for pressure measuring instruments、 converting pressure into displacement or force. The corrugated pipe has a thin wall and high sensitivity、 with a measurement range of tens of pascals to tens of megapascals. Its open end is fixed、 the sealed end is in a free state、 and auxiliary coil springs or springs are used to increase elasticity. During work、 under the action of internal pressure、 it elongates along the length direction of the pipe、 causing displacement at the movable end in a certain relationship with the pressure. The movable end can directly indicate the magnitude of pressure by driving the pointer. Bellows are often combined with displacement sensors to form pressure sensors that output electricity、 and sometimes used as isolation components. Due to the significant volume change required for the extension of the corrugated tube、 its response speed is lower than that of the Bourdon tube. Bellows are suitable for measuring low pressure
