MAGNETICALLY OPERATED Microdelta9 differential pressure devices utilize a magnetically operated actuation mechanism to indicate when the preset element differential pressure has been reached. The magnetically attractive forces act through solid metal walls of the indicator housing precluding the need for external dynamic seals and their associated fluid leakage paths. Rare earth magnets are used in Microdelta differential pressure devices for their strong magnetic forces and good shock and vibration resistance. Microdelta differential pressure devices uti- lize an internal seal on the pressure...

MICRO DELTA® differential pressure devices sense the differential pressure directly across the filter element. At a preset P, the indicator will actuate, signalling the need to change the filter element. This permits maximum use of the element, requiring element changing only when the full dirt holding capacity is reached, rather than changing elements on a periodic time basis which may result in premature disposal of "still useful" elements. Microdelta differential pressure devices actually reduce plant operating costs by signalling the need for element replacement only when the elements have...
