Description

Technical Field

[0002] Bellows are widely used in construction, factory production, and instrumentation. Their main purpose is to be used as measuring elements for pressure measuring instruments. They are elastic and can convert pressure into displacement or force. The wall of the bellows is thinner and more sensitive, with a measuring range of tens of Pa to tens of MPa. The open end is fixed, the sealed end is free, and an auxiliary coil spring or reed is used to increase the elasticity. When working, the tube is stretched along the length of the tube under the action of internal pressure, causing the movable end to produce a displacement that is related to the pressure. It is often combined with a displacement sensor to form a pressure sensor with an output of electrical quantity, and is sometimes used as an isolation element. When processing bellows, it is necessary to measure the diameter of the bellows and the thickness of the bellows wall. However, the existing measuring equipment can only measure the diameter of the bellows or the thickness of the bellows wall at a time, which is not convenient to use.
