Subject: LF: RE: Soil Conductivity
Measurement
Uwe, I would be very
interested in a plot of how the conductivity has varied over the year and in
what the largest variation of maximum to minimum that you have found?
It would also be
useful to measure at a frequency closer to 136Khz for comparison purposes?
It would have to be at a frequency away from interference and the test
signal would have to be strong enough to overcome interference.
Has anyone on the
list experience in measuring ground conductivity at such
frequencies?
Mike ?

I´am mesuring ground conductivity
over almost 1 year regularly
today it was 15,6 Ohm / m (
measured with 16Volt@ 50Hz )
I try to built a measuring device
with other frequency , somthing odd ( no multibles from 50Hz, thinking
about 111 Hz - )
and automatic daily measurements (
at present times done manually)
Would like to discuss about
it
