Re: [TCML] Tesla coil EM Gauss readings

[Ed Phillips <evp@xxxxxxxxxxx>]

Hi,

Most Gauss meters use Hall effect sensors such as the Allegro A1321LUA-T 
or DK part 620-1024-ND which they are out of.  But they don't work past 
30kHz so not not much help.
If you have a scope, you would be best off just winding a field pickup 
coil yourself and using the pure physics to calculate the field through 
the coil that corresponds to the generated voltage (or current if 
shorted).  A DVM would work too if its AC range had high enough bandwidth.

   OK - I think the use of the pickup coil is the best way to go.  
However, I'd sure be worried about bringing the DVM around a TC!  
Because the signals are pulsed decaying sinusoids there is a problem in 
interpreting any readings of the meter.  If the signals are big enough a 
diode rectifier with capacitor across the meter would simplify matters 
and the actual readings could be checked by observing the peak voltages 
with a scope.
