Murphy pd8100

The PD8100 Series eliminates pointer flutter on pressure indicating SWICHGAGE® devices which are subject to pulsating pressure from reciprocating pumps or compressors. It also allows a close setting of high and low contact points providing for more accurate pressure indication and control of equipment.

The PD8100 Series decreases wear on geared movements and increases the life of pressure indicating instruments by eliminating excessive gage strain and unnecessary movement.

Features
• Used On Controllers, Instruments and Recorders to Dampen Pressure Pulsation
• Eliminate Gage Pointer Flutter
• Aids In Providing More Accurate Pressure Indication
• Decreases Wear On Gage’s Geared Movement
