Undirected response transducer of magnetic field induction

This paper present the concept of the transducer for shape reconstruction and magnetic induction measurement of periodic arbitrary shape wave magnetic field. The measuring head consists of three coils with separated leads. Coils are fixed perpendicularly one to the other. Coil output voltages are synchronously sampled and the input samples are processed according to the algorithm developed. The characteristic curve of the transducer is theoretically deduced. Algorithm fixing signs of currently reproduced output samples of reconstructed shape wave is commented. Most significant uncertainty sources of the circuit thrust by essential blocks of signal processing path are analyzed. It was confirmed by simulation that the reconstructed wave shape and calculated induction value are independent of angle setting of measuring head in magnetic field. The transducer sensitivity to the angle setting in the magnetic field is very small.
