Measure principle of DX-2012R magnetic field mapping equipment
The space magnetic field distribution measuring instrument is mainly composed of an industrial computer (measurement software), motion control system and data acquisition system.
First, the test command is sent through the industrial control computer to control the motion control system to complete the set motion trajectory, and simultaneously control the work of the data acquisition system. The data acquisition system collects data in the X, Y, and Z directions through the Hall sensor, and then transmits the data to the industrial control system. The computer performs data processing and finally obtains a three-dimensional magnetic field distribution map.
