Supporting array device of metal Hall probe and installation method

The embodiment of the invention provides a supporting array device of a metal Hall probe and an installation method. The supporting array device is used for improving the space utilization rate so as to provide high-precision magnetic field measurement. Comprising a radial array arc-shaped body which is provided with a plurality of first metal Hall probe holes; the plurality of first metal Hall probe holes are used for placing metal Hall probes for testing the radial Br magnetic field direction, and the setting direction of each first metal Hall probe hole corresponds to the induction direction of one metal Hall probe for testing the radial Br magnetic field direction; the polar array arc-shaped body is provided with a plurality of second metal Hall probe holes; the second metal Hall probe holes are used for placing metal Hall probes of which the test poles face the Bp magnetic field direction, and the setting direction of each second metal Hall probe hole corresponds to the induction direction of one metal H
