Abstract
A moisture detecting apparatus comprising an input port; an output port; a housing that is configured between the input port at a first end and the output port at a second end; an adsorbent material that is configured in a flow path of an inner cavity within the housing; and an electrical port comprising a controller that is coupled to the adsorbent material via one or more pin bars, wherein the controller is configured to (i) measure, using the one or more pin bars, one or more voltages on the adsorbent material and (ii) determine an electrical property of the adsorbent material based on the one or more voltages.
Claims20
A moisture detecting apparatus comprising:
- an input port;
- an output port;
- a housing that is configured between the input port at a first end and the output port at a second end;
- an adsorbent material that is configured in a flow path of an inner cavity within the housing;
- and,
- an electrical port comprising a controller that is coupled to the adsorbent material via one or more pin bars, wherein the controller is configured to (i) measure, using the one or more pin bars, one or more voltages on the adsorbent material and (ii) determine an electrical property of the adsorbent material based on the one or more voltages.
A moisture detecting apparatus comprising:
- an input port;
- an output port;
- a housing comprising a filter core that is configured within the housing, wherein the housing is configured to receive a fluid from the input port that passes around or through the filter core to the output port;
- and,
- a connector hub that comprises one or more electrical connectors that are coupled to the filter core via one or more electrode strips that are configured on a surface of the filter core.
A method comprising:
- measuring, by a controller, one or more voltages of an adsorbent material that is configured in a fluid system, wherein the one or more voltages are (i) caused by inducting a current on the adsorbent material and (ii) received via one or more pins that are in contact with the adsorbent material;
- determining, by the controller, one or more electrical property values based on the one or more voltages;
- determining, by the controller, a presence of moisture in the adsorbent material based on the one or more electrical property values;
- determining, by the controller, a net change ratio based on the one or more electrical property values and an initial electrical impedance or resistance value that is associated with the
- adsorbent material in a complete dry state;
- and, generating, by the controller, a status message based on the net change ratio.
