Differential Pressure Indicator
 |
Memory
All visual indicators show whether a preset differential pressure has been exceeded at any time – even after the system is shut down. When the factory-set differential pressure is exceeded, the red button pops up and stays up until it is manually reset. When the differential pressure is reduced, the range spring returns the piston assembly to its normal position; however, the gap between the magnet and the now extended indicator button is too great for magnetic force to overcome the button spring force. The button, therefore, remains in the extended position until differential pressure is reduced and the button is manually reset. |
Pall RCA series differential pressure indicators signal the need for filter element change by sensing the differential pressure between ports upstream and downstream of the filter element. They connect to the DeltadyneTM device port available on Pall filter housings
