Temp Probe Placement?

Postby bakofsky » Sat Aug 22, 2009 10:14 am

On brutus inspired systems it looks like most folks are placing their temp probes in stainless tees attached to the kettle valves.
So doesn't the valve have to be open anytime you want to monitor temp? It seems like it would make more sense to place the T between the kettle and valve, so that you could run a longer probe all the way int the kettle, then have the valve attached to the bottom of the tee. (oriented vertically instead of horizontally).

Any thoughts?
Thanks!

Since it's direct fired, I would assume that your valve would be open during the entire mash with the pump recirculating. That's what I do. I have my probe stuck in the return manifold (see Gumby1974's post on the Northern Brewer forum) and it seems to work relatively well. I copied what Mike did for his system. Here's a link http://forum.northernbrewer.com/viewtopic.php?f=1&t=58808&hilit=+Valves+Gas+burner. I live near Mike and in talking to him I found out that he had his initially through a thermowell into the mash tun and it was not very responsive. If you want, I can take some pics of my brewtus inspired syste to show you what I'm using. It's a pretty simple solution to something that I think we tend to over complicate from time to time.

Hope that helps.

In this instance, the LOVE's only job is to monitor and control the recirculation temperature. Not monitor the mash temp itself actually. That's why I have a handy dial on the pot. :)

In general, once the mash temp is reached, it will maintain... In general.

So if one wanted to ensure that the step temp, or mash-out temp, or even simply maintaining the set mash temp in a recirculation system, you want the probe as CLOSE to the heat source as possible to ensure that the return never exceeds your actual set temp. This way the mash itself has to play catch-up to your set point, but never be able to exceed the set point.

in lonnies set up he is doing a continous recirculation with his mash so the probe is placed after the valve.
