Found what I was looking for... I'd use 2 of these, one for a low water alarm/light and a second lower on the sight glass to cut power to the element.

These are strap on and I'd have to see if they would fit on a 20 gal blichmann.

No Holes, but they are probably pretty expensive. Ill have to look at automation direct to see if they have an equivalent.

Those are the bee's Knees, if they work as listed. Had no idea they existed. Let us know how you make out with them.

The problem I see is 1) physical size...will it fit? 2). There are space requirements behind and to the side of the sight glass...hope the don't "get confused" by the pot and sight tube protector

I'll report back.

Update: I measured the blichmann 20 gal Sight glass protector. Looks like its about 23mm inside edge to edge, so I think the 20mm version will strap right on and hopefully give me a nice easy clean solution. I post pics when I get the units in.

Reason: New Info

I think I've seen the same on e-bay for about $10..
Picked one of the dented ones up for $14.95 after shipping. It is NC contacts, but you can flip the assembly upside down to make a NO like we would need.

Received parts today. Unfortunately, the sensor is about .5 mm too wide...damn. Have to re-evaluate.

They'll certainly work on a stand alone sight tube though.

I don't know, but just another thought here, two small (18 gauge) solid (not stranded) wires with only the insulation stripped off the first 1/4" of each end can be pushed through the sight glass to your heating element cut off level (stagger the wires so that one is lower than the other so the stripped ends can't touch) and these wires can be hooked up in series on the control wire that activates the relay that turns on your heating element. The wort acts like a conductor. Just a thought.

that's interesting.. my espresso machine uses something similar to that I think, there's just a piece of metal in the fill tank that when the water level drops below that point the machine goes to sleep until you fill it up.

I'm pretty sure that would trip your GFCI. If the wort conducts, the a path from those wires to ground would exist via the groud wire on the kettle (which is also touching the wort).
