This article presents the results obtained when a Duralumin plate with a slot was scanned with an inductive probe in order to measure the eddy currents' magnetic field. A 3D finite element numeric model was used to preview the eddy current distribution. An analysis of the produced data and of the consequences of using image filters is included.
In this work a novel inertial sensor is presented, which can be used as a low band accelerometer, a vibration sensor or an inclinometer. The device consists of a glass plate filled with deionized water surrounding a small volume of ferrofluid; a permanent magnet is used to fix the position of the ferrofluidic mass in a compliant position. The effect of an external stimulus can be estimated by measuring...
A tilt-sensitive measuring system exploiting a flux-gate sensor is described. The sensing configuration has been investigated using an electromagnetic modelling software first. Then, the prototype characterization has shown a system sensitivity up to 2.3491 V/deg and an Integral Non Linearity (INL) down to 1%.
