Ad7750
Hi all,
Was fascinated by the AD7750 Product to Frequency converter that was
discussed on this board couple weeks back.
Its way out of my league, but I was thinking about hooking up that circuit
shown on the page 13 of spec sheets.
Was wondering, once I got familiar with the circuit if it could be adapted
to measure the power output from an induction heater coil.

The short answer, I think, is... no.
Induction heating is done usually with radio frequency energy
which is outside of the capability of the AD7750.
You need a directional wattmeter which can give you the
net power delivered to the induction head - this is because
in the transmission line to the head you have a forward and
reflected component of energy. It's a bit complicated and
probably not a subject for this list... [noparse][[/noparse]involving neither
Linux nor Win2K :-) ].
