Anisotropic magnetoresistive sensor can be used to measure DC and AC current by sensing the field near the conductor in a contactless way. In order to improve measurement accuracy, an analysis of the influence of the displacement of the examined wire is made. According to the result of the analysis, restriction on the displacement of the examined wire is(More)
The anisotropic magnetoresistive (AMR) sensors provide an excellent means of measuring both linear and angular position and displacement in the earth's magnetic field. The electrical output of these sensors is proportional to the magnetic field strength along its sensitive axis. When such a sensor is spun around a horizontal plane starting from magnetic(More)
The anisotropic magnetoresistive (AMR) sensor is one type that lends itself well to the earth's field sensing range. The key benefit of AMR sensors is they can be bulk manufactured on silicon wafers and mounted in commercial integrated circuit packages. But the sensitivity of AMR sensor changes greatly with the temperature of surrounding and cross-axis(More)
