ABSTRACT:
The invention produces contactless radial position sensors having an equivalent angular aperture greater than 90°, and substantially eliminates the spurious microvibrations due to the imperfections of the current sensors. For this, the invention uses at least four independent sensors and an electronic device capable of virtually placing in series said sensors in groups of two or three in order to spread the equivalent angular aperture of said groups of sensors.
