Product Introduction
Bellows are tubular elastic sensitive elements connected with foldable wrinkles along the direction of folding and expansion. Bellows are widely used in instrumentation, the main purpose is to fix the open end, the sealed end is in a free state, and the use of auxiliary coil springs or reeds to increase the elasticity. When working, it elongates along the length direction of the pipe under the action of internal pressure, so that the movable end produces a certain displacement related to the pressure. The moving end drives the pointer to indicate the pressure directly. The bellows are often combined with displacement sensors to form pressure sensors with electric output and are sometimes used as isolation elements. Because the extension of bellows requires a large volume change, its response speed is lower than that of Bourdon tubes. Bellows can be divided into metal bellows and non-metallic bellows according to the composition material; According to the structure can be divided into single layer and multi-layer.
