Congrats on the first post, welcome to HBT! Do you work in the process industry? Not many people have a few guided wave probes just laying around Are they hard to interface with?

Haha, worthy thread for a first post! I work in the bio-pharma business, being a mechanic/instrument tech sure has it's advantages when it comes to "leftovers" for projects such as ridiculously overkill (but totally necessary!) brew rigs.

We use Magnetrol probes pretty much exclusively. Very easy to interface, extremely reliable, and the newest versions seem to penetrate foam quite accurately. As cool as they are, I love your approach with the backup sensor. That is the kind of ingenuity that fuels these homebuilt breweries.

I just finished wiring my control panel up and I've already got a complex after looking at yours. Too nice! I'll post a thread for mine later this week, but damn - nice job!

TFB, your work is incredible!

Also love the pics from your brazing thread. So, how much would you charge to hook a local brotha up with some fine fittings on a keggle?

Beer is the mind-killer. Beer is the little death that brings total obliteration. I will face my beer. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see it's path. When the beer has gone there will be nothing. Only I will remain.

That backup sensor may be shelved for a while if the standalone tank level probe works as well as I hope it does.

Thanks, I wouldn't mind helping out with some fittings provided I had the time... Time is an extremely precious resource right now. Maybe more towards summer.

As promised, here are the pictures from my first electric brew. Brewed the Norther Brewer Pro Series Town Hall Hope and King Scotch Ale, one of my personal Minneapolis favorites. Tonight I brew the Surly Furious copy, my personal favorite

For starters, I drilled a hole in the bottom of my HLT and added on a 3/4" triclamp ferrule for the drain.



Then I finished up the heating element enclosure wiring with a nice strain relief.



Next I setup my microcontroller circuit to adjust the heating element power. This is very ugly right now but it performed perfectly. With the potentiometer I am able to set the duty cycle of the element between 0-100%. All of this equipment will eventually make its way into the HMI on a dedicated circuit board. The code was hacked together over the last couple nights... I am new to this processor but there were some great examples that kick started my development.



Here is how the inside of the PCU turned out with just one of the outputs wired up. Everything worked great, first electric brew was a complete success!

Looks good, but where's the picture of that "Sweet Wort" being boiled?

I'll be sure to take a picture later tonight on brew #2. The 4500W element for the HLT was pretty speedy... not looking to go back to propane anytime soon.

Default Been working on the use of electricity myself

well... i use a much cheaper... say ghetto way to do this... i use two heating elements for my boil kettle (240 volts) with a dimmer switch for lights on each leg of 120. works ok for temp control for mashing. Though I just use straight connections for my boil kettle due to the fact that these dimmer switches cant really handle the wattage for that.
