4.1 General Remarks
4.1.1 Magnetic Field Sensors—Classification
Most of magnetic sensors are really sensors of ux
density of magnetic eld
*
—there are some sensors that
measure other values by magnetic principle, for exam-
ple, magnetostrictive sensors of pressure. Figure 4.1
presents sensitivity ranges of the most commonly used
magnetic eld sensors (MFS).
Author of this book presented in the past a review
of MFS (Tumanski 2004). There are also other reviews
presented by other authors (Lenz 1990, Heremans 1993,
Lenz and Edelstein 2006, Ripka and Janosek 2010) as well
as review books (Boll and Overshott 1989, Ripka
