Abstract
Various embodiments are directed to isolation devices, systems, methods and various means, for isolating ignition causing signals and/or explosions from hazardous or explosive environments.
Claims20
An isolation device disposed in electrical communication between an isolated component and an exposed component, the isolation device comprising:
- a protective housing comprising a wave coupler chamber, wherein the protective housing comprises a base metal having a first conductivity and a conductive interior surface having a second conductivity, wherein the second conductivity is greater than the first conductivity;
- a transmission coupler positioned within the wave coupler chamber, wherein the transmission coupler is configured to transmit an electromagnetic wave into the wave coupler chamber following receipt of an input signal generated by one of the isolated component or the exposed component;
- and
- a reception coupler positioned within the wave coupler chamber, wherein the reception coupler is configured to transmit a coupler output signal to the other of the isolated component or the exposed component upon receipt of the electromagnetic wave.

An isolation device disposed in electrical communication between an isolated component positioned within an environmental enclosure and an exposed component positioned outside the environmental enclosure, the isolation device comprising:
- a protective housing comprising a wave coupler chamber, wherein the protective housing comprises a base metal having a first conductivity and a conductive interior surface having a second conductivity, wherein the second conductivity is greater than the first conductivity;
- a transmission coupler positioned within the wave coupler chamber, wherein the transmission coupler is configured to transmit an electromagnetic wave into the wave coupler chamber following receipt of an input signal generated by one of the isolated component or the exposed component;
- a reception coupler positioned within the wave coupler chamber, wherein the reception coupler is configured to transmit a coupler output signal to the other of the isolated component or the exposed component upon receipt of the electromagnetic wave;
- and
- a dielectric at least partially filling the wave coupler chamber.
