摘要： 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.

摘要： According to one embodiment, a sensor includes a structure. The structure includes a base layer, a first film, and a first layer. The first film includes at least one selected from a group consisting of silicon and aluminum, and oxygen. At least one of a volume of the first layer or an electrical resistance of the first layer is configured to change according to a detection target around the structure. The first film includes a first film region, a second film region, and a third film region. The first layer is between the base layer and the first film region in a first direction from the base layer to the first film region. The first layer is between the second film region and the third film region in a second direction crossing the first direction.

摘要： An apparatus for measuring volumetric moisture content using an affixing method for sensing probes that reduces bending and breaking stress on the probes. The volumetric moisture content sensor has sensing probes secured against compressive axial movement during insertion into a test media, while allowing limited radial movement. Radial movement is limited via the use of a compressed elastomeric sleeve surrounding the portion of the rod supported by the sensor housing. When in the uncompressed state, there is a clearance fit allowing free movement for removal and replacement of the probes. The compressed elastomeric sleeve is used in conjunction with a rod support mechanism such that the sleeve seals out moisture, dust, and other contaminants from an interior portion of the sensor. The compressed elastomeric sleeve provides a force that assures a proper electrical connection between the sensor probes and an electronic circuit of the sensor.
