WebThe first and second AMR sensor element outputs are combined to derive a sensor response which is substantially anti-symmetric in the region close to zero external magnetic field. This arrangement shifts the zero detection point of the AMR sensor elements away from a maximum of the response curve, so that sensitivity in proximity to a zero input … WebA Hunt element is not sensitive at small field strengths. In order to make the MR sensor sensitive for low magentic fields, the MR transfer curve (1) has to be modified. The most common way is achieved by barber poles (see Figure 2.) Small, highly conductive bars – the barber poles – are placed on top of the Permalloy.
