Application of resonant sensors for magnetic flux density measurements

摘要

This contribution discusses the influence of the magnetic flux density on Lorentz force driven resonant sensors. A closed form model describing the physical behavior of the resonating wire shows the quadratic influence of magnetic flux density on the readout signal, which in our case is the motion induced voltage in the oscillating wire. It is furthermore shown that the resonating wire sensor is well suited for magnetic field measurements, even at high temperatures.
