looking for complete mechanical designs of gradiometer

[Atul Asthana]

I am looking for mechanical designs and related issues on building a gradiometer.

Any references, articles or studies, even college experiments will be helpful.

Thanks, I did do a search on Google and read a lot of articles.

I am looking for specific mechanical designs, where the effect of cabling, cable quality, baseline dimensions, mechanical stability, electrical noise reduction (specially under power lines, use of Faraday shield, alignment of cores etc. has been analysed.

A constructed design will be of great help.

Very simple DIY fluxgate gradiometer using two cheap axial inductors: http://www.elektronik-labor.de/Notizen/Fluxgate.html

MAG SHIELD. Take look at www.fgsensors.com. You can buy KIT (or make PCB at home) also program for arduino is for free.
