Default How do I instal this RTD probe in my kettle?

Liquid tight RTD sensor, 2 in, 1/4 NPT Thread [PT100-L50NPT] - $31.55 : auberins.com, Temperature control solutions for home and industry

Can I install this as a weldless kit? Has anyone used this model?

You can install it on T joint at kettle output.
If you intend to put it on kettle you"ll need washer and o-ring with lock nut.

A T joint would probably be the easiest. You could also weld in a 1/4" half coupling, but if you want to go weldless listen to diS. Check this out for more info: Temp Probes

I installed it on a T with my site glass. Brewed for the first time with it yesterday. Problem was that it wasn't long enough to pass through the T and into the kettle. Even with recirculating, my temps were reading 10-15 degrees behind the rest of the kettle as I was heating.

I will probably have a 1/4 inch half coupling welded on so I can get better readings directly in the kettle. Having it on the output might work better too as long as I'm recirculating.

If its for your kettle I wouldn't put it in a tee output. I soldered a 1/4npt lock-nut to mine, but you could do a weldless set-up if you wanted. http://www.mcmaster.com/#stainless-s...cknuts/=fqa8xn

I had a 1/4" k type thermocouple in my keggle and you really need to mix up the water/wort to get an accurate reading. I just ordered a 2" rtd temp probe with weldless bulkhead from auberins.

What do you guys think about using the 4" 1/4 NPT temp probe in a sight glass tee? If you use the sight glass they sell at Brewhardware it has a 1/4" NPT thread for a thermometer. I would think that the probe would extend at least 2" into the kettle.

I actually have the 4 inch. With the half coupling, nipple, tee and reducer to get through, it doesn't stick into the pot at all.

I dont think that probe would make into the kettle through the tee.

I just installed the weldless sightglass T from Brew Hardware you linked above this past weekend. Have the 4" 1/4 NPT thermocouple rather than the RTD installed. Didn't get a chance to test out its accuracy, but can confirm that the probe extends into the kettle. It's not in front of me, but I'd say by about 2".
