Abstract
An apparatus for measuring humidity of air flowing in a conduit includes a probe comprising a probe arm configured to be inserted into the conduit. A humidity sensor element is disposed at a distal end of the probe arm. A filter is connectable with the probe arm to enclose the humidity sensor element. The filter includes a filter housing that defines an interior in which the humidity sensor element is disposed, and an opening that provides fluid communication between the interior and exterior of the filter housing. The filter further includes a filter membrane that spans the opening. The filter membrane is constructed of a hydrophobic material that allows air and water vapor to pass freely through its structure from the exterior to the interior, and that blocks liquid water and particulates from passing through its structure from the exterior to the interior.
