Abstract
A system, method and device may be used to monitor conditions in a borehole. Energy is transmitted to a pulse generator located proximate a position to be interrogated with a sensor. The pulse generator stores the energy, then releases it in a pulse of electromagnetic energy, providing the energy to resonant circuits that incorporate the sensors. The resonant circuits modulate the electromagnetic energy and transmit the modulated energy so that it may be received and processed in order to obtain the desired measurements.
