PRESSURE DETECTION SYSTEM IMMUNE TO PRESSURE RIPPLE EFFECTS

摘要

A filter assembly for a fluid flow system includes a filter housing (22), a housing inlet (24) to allow the fluid flow into the filter housing and a housing outlet (26) to allow the fluid flow to exit the filter housing. A filter element (34) is located in the filter housing to collect contaminants from the fluid flow. A pressure sensor (36) is located to measure a pressure drop across the filter element. The pressure sensor includes at least one sense line (44) extending into an interior volume (50) of the filter housing. A method of monitoring a filter assembly for a fluid flow system includes positioning a pressure sensor at a filter assembly, extending at least one sense line from the pressure sensor into an internal volume of a filter housing of the filter assembly, and measuring a pressure drop across a filter element of the filter assembly via the pressure sensor.
