Clog resistant low pass filter for a pressure transducer

Abstract

A reconfigurable pressure transducer assembly having an input tube filter assembly is provided. Multiple small inlet apertures of the transducer housing or input tube filter assembly may be utilized to filter particulate matter from the measurement media/fluid. The resonant frequency and dampening characteristics of the pressure transducer assembly may be configured by the input tube filter assembly such that temporary clogging of a portion of the small inlet apertures does not appreciably affect the resonant frequency and dampening characteristics. The input tube filter assembly includes one or more inserts disposed in an input tube channel, the one or more inserts including one or more apertures of selectable dimensions and extending therethrough from a first end to a second end. The one or more inserts define at least a filter aperture, and the input tube filter assembly is tunable by selection of the selectable dimensions of the one or more inserts.
