The paper aims to explain the operating principles of fluxgate magnetometers.
The approach is to describe the uses of ring fluxgate magnetometers and their operating principles.
The operating principles of fluxgate magnetometers are poorly understood and their applications potential seriously undervalued. An increasing number of everyday applications relying on sensing and fluxgates, in conjunction with modern analogue and micro‐controller electronics, represent unique value in implementing a variety of low‐cost, precise and absolute sensing elements. As magnetometers they are small, robust, reliable, low‐cost and can resolve flux densities to nano Teslas. This can be exploited to make a variety of sensors which are precise, inherently non‐contact and, for rotary sensing, have full 360° operation.
The paper illustrates how fluxgate magnetometers can form the basis for a variety of robust, reliable, non‐contact industrial sensors.
