RTD Probe Weldless Connection

[hio3791]

I bought the Liquid tight RTD sensor, 1.5 inch, 1/2 NPT Thread from Auber for my BK build. It didn't come with o-ring or locknut.

This may be a simple question but what did you use to attach it?

Would this work:

1/2 inch o-ring/locknut/washer

From the tutorial on theelectricbrewery.com, looks like Kal uses a wide o-ring on the outside of the kettle with a locknut on the inside (no washer). Is that a better water-tight solution? In that case, would this work:

Large 1/2 inch o-ring and get a 1/2 inch locknut to go with it?

I am probably over thinking this.

I suggest that you use this probe instead.

do they makes these in K type

thanks

Well, I just had a :smack: moment. I called Auber and they'll exchange the sensor for this one. They said the fitting is different (I presume for fitting into a tee, etc) so just getting a gasket and nut may not have worked.

Thank you PJ.

Not that I know of but wouldn't hurt to call and ask. I was going to go with a K-type but I specifically like the deluxe cable option and how it is detachable.

You are very welcome. I'm glad we caught it as it will save you a lot of grief.

The only difference I see it the size of the hole being 1/2 NPT (american standard) on the first one vs the smaller european m14 threads and a longer probe on the one pj linked.

I have both types (without the quick disconnect and either works fine depending on the size of the hole in your pot or fitting... actually the 1/2" silicone rings and threaded nuts are easier to source in the US.
but yes the orings and nuts linked in the first post would have also worked fine... I actually like my 1.5" probe much more than the longer ones I have in my MT and HLT.... Its easier to stir and clean around without it sticking so far into the pot.
I also worried about the fact that the solid outside lip was not as large to seal against the pot correctly but it ended up being a non issue as they dont leak in either of my applications.

I dont believe you can change the cable length on the k type... I could be wrong.

That's correct but the one being NTP is designed to be used in a fitting, like a tee, etc. If you look closely at the other one, having the smaller threads, it has a flange which nicely seals the gasket against the kettle. The NTP one doesn't making it difficult to be used as a weldless fitting.

I shipped it back yesterday and should have the replacement sent soon. Either way, I am still collecting parts and haven't started building anything yet.

I agree, I like the smaller probes. Being that it's going to be used in a BK, it doesn't need to be any longer.

There is another major difference between the two probes. The first is a NPT (National Pipe Thread) fitting. The second is a straight metric thread and provides an easy way of sealing it to the pot by design. A tapered thread in the same situation could be a major PITA when setting it up.

But to each their own...

Ahh yes I see now that its tapered.... mine are not noticably tapers like that if at all.... the nut went on with little resistance , in fact I even put teflon tape around the base...
I never said my way was superior just that the concerns in the original post are a non issue in practice and either way works fine..
just as my $6 RTD work great but with the inconvenience of having a cable permanently attached and the plug at the control panel end... If I wanted to spend an extra $100 on three of these it would have made cleanup easier for sure. But I simply had to save where I could. another plus to plus keeping everything on the same 1/2" standard makes it easy to move thing around and rearrange later if needed..
