中文摘要	A rectangle pulse signal was used as the excitation signal to drive the resonator of a resonant sensor. The freely decaying oscillation signal, in which both the resonant frequency and the resonant damping information are carried, is sampled and processed to obtain both the resonant frequency and resonant damping coefficient of the resonator at the same time. An experimental rig for such a pulsed dual-parameter measurement method is set up with an eddy current distance sensor tested as an example. Tests show that during the distance measurement, both the resonant frequency and the resonant damping coefficient can be obtained simultaneously. This pulsed method can be used not only in eddy current sensors, but also in other resonant sensing systems.
