Application of Multi-Dimensional Hall Sensor for Gauss Measurement

Abstract

This paper reported on a two-dimensional Hall sensor enabling to measure the two spatial components of the magnetic field and applied for gauss measurement application. The device was operated through only five contacts and tested by varying the magnetic flux density from -5000 to 5000 Gauss (G) and using signal conditioning circuitry for amplifying and adjusting the both similar sensitivity. After that, the output signals were converted to digital signals by ADC for transmitting a computer using LAB-VIEW programming and comparison with the standard gauss meter (F.W.Bell5170). The result of gauss measuring application comparison with the standard gauss meter has done with a precision of 0.04-3.80% including a calibration process.
