Pneumatic Filter

摘要

A tuned sensor system is disclosed. The tuned sensor system may receive an unsteady pressure from an external environment via a pressure inlet port. The pressure may have a first component that is substantially static and a second component that varies at a relatively high frequency. The pressure inlet port may conduct the unsteady pressure to a tuned path. The tuned path may filter the unsteady pressure, blocking the second component and communicating the first component, such as for use by a pressure sensor. The tuned sensor system may be compact and may include one or more turn in the tuned path so that the distance between the pressure inlet port and the sensor is less than the length of the tuned path. The tuned path may be entirely within the supporting structure of the tuned sensor system, easing installation, removal, and maintenance of the compact and modular system.

主权项

1. A modular tuned sensor system comprising:
a main body having a tuned path in fluidic communication with a pressure inlet port; an enclosing member having a substantially planar structure defining a portion of the tuned path of the main body and substantially sealing the tuned path from leaking; and the pressure inlet port having an aperture disposed in the enclosing member; and a sensor terminus having an aperture defined through the main body and in fluidic communication with the tuned path.
