Technical characteristics and application of magnetic sensor array
Magnetic measurement technology has been applied to more and more fields, but there are still disadvantages of independent magnetic sensors in terms of cost and performance. In order to improve the performance of the measurement system, expand the spatial range of measurement, and realize deeper utilization of magnetic field information, magnetic sensor array technology has gradually developed. This paper collates and summarizes the application of array magnetic sensor technology in several fields, and concludes that magnetic sensor array technology has the advantages of large measurement range, high accuracy, good reliability, etc., and the disadvantages of cost and control difficulty, position calibration error and noise interference. Finally, the development prospect of magnetic sensor array technology is prospected.
