A shunt on AC will give you an AC voltage proportional to AC current. If
your monitoring device is OK with AC input then, yes, you can do it that
way. But if it is a sitemonitor, I don't think it will like AC so much.
And the output will have reference to the AC, in other words it will be hot.
Normally you use a current transformer to measure AC. You can follow up the
current transformer with a diode bridge and cap or get one that has a DC
output.

Not sure the range of the inputs but yes, if an input has a voltage range
that will cover your thermocouple it will indeed read it.

Subject: [AFMUG] Dumb shunt question
This might be a dumb question:
Can I use a packetflux current shunt to measure current on AC, or are
they strictly for DC?
Ok, I have a second dumb question:
The shunt input on a Site Monitor II is just measuring microvolts
right? So if I'm not using it for a shunt, can I instead use that for a
thermocouple temperature probe?
