Dear sir,
We are working on gear box health monitoring project. And wanted to sense changes in magnetic flux densities due to gear tooth interaction with magnetic field. (gears are made up of ferromagnetic material like mild steel).
Basic idea is, we need a sensor which will sense the changes in magnetic field whenever tooth pass by. We are thinking to place magnet near one side of tooth and other side will place sensor. So whenever tooth pass by it will have some effect on magnetic flux densities. and by sensing those changes we can track health condition for each tooths.
We calculated the changes in field strenghts by using laboratory gauss meters.For our particular configuration We found that the field strenghts varies between 65-125 guass.
Now we need a magnetic field sensor with sensing range nearby above mentioned range. so that we can include it in our project.
Kindly suggest us best suitable sensor for our application. As this is R & D project we can do modifications so suggest if you have any ideas.
Thank you
