I'm trying to use IC hall effect sensors for a school project *not homework, rather an ungraded research project*. Basically, we are trying to measure the magnetic field gradient inside of an experiment chamber. The chamber is surrounded by two huge copper coils that have about 1000A running through them - the magnitude of the B field is ~900 gauss max. Problem is, the only hall effect sensors i can find max out at around 800 gauss. The sensors we are trying to use now are made by optek (3150), and are easy to use but have too high of a sensitivity. Is anyone familiar with a way we can extend the range of fields we can measure? I thought about using magnetic shielding (wrapping the sensors in mu metal or something similar), but this is problematic and I was hoping for a more accurate solution. Any suggestions?
