◎Applications Description

The product is suitable for severe and corrosive environment. A safety clapboard is installed inside the gauge. There is pressure relief cover and hole on the back that can set free the inside pressure which might break the elastic element because of over-loading. It enhances safety for staff and facilities.

Oil-filled safety pressure gauge is shock resistance and damping, which can prevent the gauge inside from being hurt by vibration and meanwhile lubricate components inside and reduce abrasion.

This gauge series is widely used in food industry, medical industry, oil refining, chemical industry, oil offshore platform, well drilling, shipping industry and so on for measuring medias which are corrosive, non-viscous or non-crystalline
