A modular tuned sensor system comprising: a main body having a tuned path in fluidic communication with a pressure inlet port and having a sensor mount comprising a structure extending from the main body and configured to support a sensor and position the sensor in fluidic communication with the tuned path; wherein the tuned path comprises a semi-circular cross section disposed in a first substantially planar face of the main body and the sensor mount extends normal to the substantially planar face; an enclosing member having a substantially planar structure with an enclosing planar face or a semi-circular profile corresponding to that of the main body defining together with the main body the tuned path and substantially sealing the tuned path from leaking; the pressure inlet port having an aperture disposed in the enclosing member; a sensor terminus located proximate the sensor mount having an aperture defined through the main body and in fluidic communication with the tuned path; wherein the tuned path is configured to receive an unsteady pressure from the pressure inlet port, and wherein the pressure inlet port is in fluidic communication with an external environment, and wherein the unsteady pressure comprises a first component with a substantially static pressure and a second component with a high frequency variable pressure, and wherein the tuned path blocks the second component and transmits the first component from the pressure inlet port to the sensor terminus; the sensor terminus is disposed at an opposite end of the tuned path from the pressure inlet port, wherein the pressure inlet port is configured to be aligned, in use, to at least one of an opening in an external surface of an aircraft and an opening in a propulsion system surface. a main body having a tuned path in fluidic communication with a pressure inlet port and having a sensor mount comprising a structure extending from the main body and configured to support a sensor and position the sensor in fluidic communication with the tuned path; wherein the tuned path comprises a semi-circular cross section disposed in a first substantially planar face of the main body and the sensor mount extends normal to the substantially planar face; an enclosing member having a substantially planar structure with an enclosing planar face or a semi-circular profile corresponding to that of the main body defining together with the main body the tuned path and substantially sealing the tuned path from leaking; the pressure inlet port having an aperture disposed in the enclosing member; a sensor terminus located proximate the sensor mount having an aperture defined through the main body and in fluidic communication with the tuned path; wherein the tuned path is configured to receive an unsteady pressure from the pressure inlet port, and wherein the pressure inlet port is in fluidic communication with an external environment, and wherein the unsteady pressure comprises a first component with a substantially static pressure and a second component with a high frequency variable pressure, and wherein the tuned path blocks the second component and transmits the first component from the pressure inlet port to the sensor terminus; the sensor terminus is disposed at an opposite end of the tuned path from the pressure inlet port, wherein the pressure inlet port is configured to be aligned, in use, to at least one of an opening in an external surface of an aircraft and an opening in a propulsion system surface.
