Abstract
A pressure sensing system and method for an engine of an aircraft include a transceiver assembly coupled to a portion of the engine, and a pressure sensor assembly coupled to a fan blade of the engine. The transceiver assembly is configured to transmit a first signal at a first frequency and a second signal at a second frequency that differs from the first frequency. The pressure sensor assembly is configured to receive the first signal and the second signal and transmit a third signal at a third frequency that is a difference between the first frequency of the first signal and the second frequency of the second signal. The transceiver assembly is configured to receive the third signal at the third frequency. A pressure in relation to the engine is determined based on the third signal.
