Dear Sirs
I would like to do something that might not be possible.
I would like to measure the thickness of metal, 20-50mm.
Ultrasonic sensors does that easily but as I understand piezo elements are fragile and my equipment will be exposed to high G-forces, shock, so I was looking into eddy current measurements.
I am not interested in measure distance to metal. My sensor will be inside the metal and I would like to measure the thickness of the metal to the surface ( wear sensor).
If distance 20-50mm is totally impossible then I could settle with just detecting that we have reached 20mm.
To further complicate things, the circuit is powered from a small battery and the coil must be small.
Is this at all possible?
Thanks
/Dan
