Abstract
Description
technical field
[0001] The invention relates to the technical field of bellows clamping devices, in particular to a bellows clamping device with adjustable aperture. Background technique
[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets made of plastic along the direction of folding and expansion. The bellows has a thinner wall and higher sensitivity, and the measurement range is tens of Pa to tens of MPa. Its open end is fixed, and the sealed end is in a free state, and the auxiliary coil spring or reed is used to increase the elasticity. When working, under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement that has a certain relationship with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form a pressure sensor whose output is electricity, and are som...
