Vibrating wire sensor measurement method by stimulation with steps of variable frequency sinusoidal pulse trains
István Kovács, Mircea Maria, Gyurka Bela-Zoltan, Szabolcs Balogh · 2012
In some cases, “pluck-read” (single coil) measurement mode of the resonant frequency of vibrating wire sensors does not lead to result. For these cases, the authors of this article have developed a new stimulation method with step of variable frequency sinusoidal pulse trains. As a result, the amortized output signal duration of the sensor will be longer, allowing the measurement of some, partially deteriorated vibrating wire sensors, which cannot be measured with other methods.
