RESONANT SENSOR MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a resonant sensor measurement device for measuring variations of at least one physical variable.SOLUTION: A device (100) for measurement of at least one physical variable comprises at least: a first and a second resonant sensor (102a, 102b), one of the two resonant sensors (102b) being sensitive to a variation of the physical variable to be measured and the other of the two resonant sensors (102a) not being sensitive to a variation of the physical variable to be measured; means (104) capable of imposing the same resonant frequency on the first and the second resonant sensors; and means (108) of measuring a phase shift between output signals from the first and the second resonant sensors.
