RADIO FREQUENCY SIGNAL AND POWER THROUGH DIELECTRIC WAVEGUIDE FOR GALVANIC ISOLATION TO HYDROGEN SENSORS

Apparatus and associated methods relate to galvanically isolating one or more sensors from a controller. Power and control signals are provided to an isolation system via RF electromagnetic waves transmitted from the controller to the isolation system via a dielectric waveguide. The received RF electromagnetic waves are converted into an RF electrical signal and then the RF electrical signal is separated into power and control signal components. The RF power signal component is rectified and regulated so as to provide power to the isolation system. A sensor interrogator is electrically connected to one or more sensors so as to receive sense signals therefrom. The sensor interrogator generates a data signal indicative of one or more physical metrics of a potentially hazardous environment in which the one or more sensors are situated. The data signal is converted to RF electromagnetic waves, which are transmitted, via the dielectric waveguide, to the controller.
