Glycerin filling dampens pointer movement and minimizes the effects of vibration and pressure pulsation on gauge readability.
Reduced pointer flutter allows operators to obtain clearer vacuum readings under dynamic operating conditions.
The all stainless steel structure improves resistance to demanding industrial environments and aggressive atmospheres.
Liquid filling protects the internal movement from shock and vibration, helping reduce mechanical wear.
As vacuum pressure changes, the Bourdon tube deforms proportionally relative to atmospheric pressure. This movement is transmitted through the internal mechanism, rotating the pointer across the dial. The glycerin filling stabilizes pointer motion by absorbing vibration and shock loads.
Liquid filling helps improve pointer stability and extends gauge life in applications exposed to vibration and pressure pulsation.
Stainless steel provides improved corrosion resistance and mechanical durability in industrial environments.
