■ Shaking of a pointer due to mechanical vibration is absorbed by viscous drag of glycerin into a gauge. Movement of a bourdon tube is also absorbed, improving absorption effect of pulsating pressure of fluid.
■ Glycerin serves as lubricating oil for a friction part of a bearing and gear in a gauge, thereby improving the durability of the internal mechanism.
■ Even if a bourdon tube is broken, a front plate isn't shattered, because oil is purged from a safety cap.
■ You can easly set pressure range and setting value by green marks on a front plate. (Only for φ60 gauge)
■ Select a pressure gauge which has max pressure scale of 2 times more than your pressure range.
