Default where to position temp probe

getting ready to order the bcs unitand trying to decide what size thermistors to order and where to place them in the keggles. I was thinking inside a t with a sightglass, would that work?.... any other ideas?
Thanks

I'm in the process of building a BCS system. I'm planning on adding a stainless 1/2" T fitting on the output ballvalve and inserting a temp probe via a compression fitting.

I ordered 4" probes from http://www.brewershardware.com. I don't know if it will work, but I'm giving it a try.

Always put temp sensors in the flow, not in the kettle. This is done for the most accurate readings, avoiding stratification.

The exception of course is the boil kettle as there's no in/out flow while boiling. The good news is that boiling causes lots of stirring so the temperature is consistent throughout the kettle (though with boiling it's not really important).

+1 on what Kal said.

I have an additional 12' probe that goes into the center of my mash tun, but the one i use to regulate my temperature is the one in line with the mash return line.

Perfect! So basicaly i can place the bk probe in a t with the sightglass and the the mlt and hlt should be place in a t on the ballvalve? Im thinking 6 in for the bk and 4's for the other two?

That should work.
Some will say the BK probe will be somewhat recessed but the wort is in such motion during boiling that it doesn't matter really. If it's 6" long then it'll stick right into the kettle enough that it definitely won't matter.

The HLT/MLT probes only need to be long long to reach into the plumbing a bit.

Mine are short:
