Wireless receptor for communications within housings
View Patent ↗The present invention provides a system and method for transmitting information between a device within a housing to a second device, preferably a test or monitoring unit, outside of the housing. There are numerous issues associated with transferring information from within a sealed housing to an external device. In some cases, the use of wires inside the housing may be impractical, due to internal conditions, such as fluid flow, pressure or temperature. In one embodiment, the antenna of the external RF reading device is electrically connected to the dome of the housing. In another embodiment, the device within the housing is electrically connected to a housing component. In another embodiment, the gasket is used to pass information from within the housing to an external device.
1. A filtering system comprising:
a housing comprising an electrically conductive housing dome and a housing base;
a filtering element located within said housing;
electronic circuitry located on or near said filtering element;
a gasket interposed between said dome and said base so as to keep them physically and electrically isolated, and to create a liquid tight seal; and
a device external to said housing, wherein said electronic circuitry and said device are both in communication with said housing dome such that said housing dome serves as an electrical conductor between said electronic circuitry and said device.
2. The filtering system of claim 1 , wherein said housing base is grounded.
