摘要：A wireless sensor including a resistive element, a modulating element located on a rotating component and at least one of a transmitting element and a receiving element, wirelessly coupled to the modulating element. The modulating element is configured to modulate the wireless coupling, between the at least one of a transmitting element and a receiving element, in response to a change in resistance in the resistive element. The modulation of the wireless coupling is indicative of a measurand on the rotating component. A method of detecting a measurand in a rotating component of a rotary machine includes wirelessly coupling at least one of a transmitting element and a receiving element to a modulating element; modulating the wireless coupling with the modulating element located on the rotating component; and calculating the measurand in the rotating component based on the modulation of the wireless coupling.
