Can I use FGM-1 for EPE Gradiometer ?

[wtrk]

As I ask the topic, I have 2 FGM 1 sensor.

My friend built EPE gradiometer for me.
Can I use these 2 sensor for EPE gradiometer ?
If yes, how I do it ?
Thanks for your advance

Yes.
Connect it at gnd, +5V and give the output at clk1 and clk2.
Or.. with other words connect it in the place of FGM3.
Read datasheets first for pins!!!

Thanks , I will try it..
So what do you think about performance ?
Do you have any idea between FGM1 and FGM3

One is more sensitive than the other, but I forgot which. Pinout is the same.

FGM3 is more sensitive bro..

Im interesting how much percent different between FGM1 and FGM3 ?

FGM1... This is a miniature version of the original standard FGM-3 type of sensor. It is essentially a three terminal device, (Gnd., +5 volts and Output) but a fourth terminal has been added which gives access to an internal over wound coil. This coil can be used to alter the zero field output frequency or as a feedback coil for linearity improvement. (see application notes). The output is in the form of a robust 5 volt rectangular pulse, whose period varies in proportion to the field along the principle axis of the device. Field Range + 0.5 oersted (+ 50 micro-tesla).

FGM3....This is the original larger version of the sensor, (60 mm long x 15 mm diameter) which has a somewhat higher sensitivity making it more suitable in some applications where size is not important. It has the same type of output as the other devices. Field Range + 0.5 oersted ( + 70 micro-tesla).
