Abstract:
1. A system for sensing a temperature in a subterranean environment, comprising: a signal generator, configured and arranged generate an electromagnetic signal; a sensor probe, locatable in a region of the subterranean environment, the sensor probe including a resonant circuit portion that includes a capacitive element, the resonant circuit portion being configured and arranged to receive energy from the electromagnetic signal and to generate a ringing signal in response to the electromagnetic signal, wherein the capacitive element of the sensor probe is responsive to a temperature condition in the region of the subterranean environment to modulate the ringing signal in accordance therewith; the capacitive element comprising: a receiver, configured and arranged to receive the modulated ringing signal; and a processor, configured and arranged to process the modulated ringing signal to obtain a measurement of the condition.
