Pneumatic indicator for detecting liquid level

摘要: A pneumatic sensor/indicator device includes a sensor assembly having bellows receiving chamber and housing. An elastic is in the chamber. shaft connects to so extension/retraction causes axial movement. magnet connected generates field moving an indicator ring. dome body. The ring housing non-indicating condition displaces into providing visible indicating condition. flexible tube extends well level sensing extending therefrom. fluid rising above inlet end increases pressure port inducing displacement causing movement toward are isolated from preventing contents entering fogging dome.
