We need to get this for our project.. it's only a part of the project. This O/P goes to the microcontroller and so on..
So the question is..
1. Is such a thing avble commercially? OR
2. Can we design using circuits??
3. OR .. Can it be done this way??
**broken link removed**
From the figure, the magnetic float is a permanent magnet, while the magnet that is connected to external circuit is an induced electro - magnet.
We have the arrangement in ,say (NorthPole-NorthPole arrangement), thereby they repel, but how to sense the change, for eg. in current change proportions etc.. ???
IS this above thing possible at all??
