Vibrating wire signals
Vibrating wire readers that only use the time series to determine the frequency may report an
incorrect frequency as a result of noise. The frequency spectrum (VSPECT) filters the noise and
easily identifies the sensor signal. VSPECT provides noise immunity by correctly identifying the
sensor signal and ignoring the influence of electrical noise that plagues time-domain-based
vibrating wire readers.
