Multiwire Parallel Fluxgate Sensors

Popis výsledku v původním jazyce

Fluxgate sensors with straight wire or rod cores are used in NDT, portable gradiometers and sensor arrays and for the detection of small objects. We show that their sensitivity at the voltage output mode depends on the excitation parameters, properties of the core material and geometry, pick-up coil length, but only slightly on the pick-up coil diameter. This finding allows to design multiwire cores with large wire pitch, which decreases their magnetic interactions and thus reduces demagnetization and correlation of their noise. As a result, using N wires theoretically increases sensitivity N-times, which is not achievable with dense cores. We have demonstrated this tendency for N up to 8 and one type of permalloy wire.
