To the Folks out here that know more than I
I have found a site that uses a sensor to measure GMR
http://www.wsrcc.com/alison/uxopaper/demo.html
Giant magnetoresistance. It would seem that this sensor would have a place in the design of a PI machine(fools rush in)
There seem to be evidence that the sensor has greater sensitivity than say a rx coil and may be imune to some of the tx signal. I may well be way off on this, but I spoke with a sales rep with the company that makes the sensors an he was agreeing to some of the idea. They also have sample kits and some docs that show a simple setup for getting a signal
Since this was used as a was of detecting iron for fining mines, my thought was that there might be a way of discriminating out the iron or even the earths noise so as to give a better signal from a non ferrous target.
Please visit the site and let me know what you think. Is it a dead end that has been tried?
Thanks Wyndham
