I am needing help picking a PID to use for my chest freezer converted into a kegerator.... I want one that will flip an SSR that turns on the freezer's condensing unit. I would like to be able to control its cycle on and off time. On for a minimum of 10 minutes. Off for a minimum of 10...

I'm looking for some perspective on this project of mine... I want to rebuild/redesign a control panel that will control every single aspect of my entire brewery. The kicker is that I want to use a PLC to replace the 48 relays I have already in place in the existing control panel. The current...

https://drive.google.com/file/d/0B7c7IZPbBYZgYm96RDRpUVkxM0k/edit?usp=sharing Working on my brewery concept a little still... Currently my "Automation" uses pids and timers from auberins along with way too many latching relays. The system must have 40 relays in all in it, and the "logic" is...

I need some help figuring out what's wrong with my two new pumps. I bought them both from PexUniverse online. They shipped brand new. When I power them both up, they just hum. The fan in the back doesn't spin, neither does the magnet. I removed the head assembly to look at the magnet, and...

I'm looking for some really sharp 22 mm on/off switches for my control panel. I thought the illuminated variety from automation direct looked great, then got my hands on them and they seem cheap and flimsy. I did some research and found some really cool 22mm anti-vandal switches from...

So I came by a bunch of this stuff in its powder form. Can it be used to make caustic and be used to clean brewery equipment- specifically stainless 304.

So this may be a better question for the equipment forum, but thought I'd post in electric. If I have a HLT build from stainless 304, employing the use of a water heater element (camco), will the element and its NPT base be able to tolerate the use of acid and caustic chemicals for...

I have a three way momentary selector switch that I want to use that ultimately does the following. When momentary selector is in the up position, it latches pathway "A", and unlatches pathway "B" When momentary selector is in the down position' it unlatches pathway "A", and latches pathway...

I like the looks of these switches... Vandal resistant push-button switch - IP65, IK09 | Série 82 - EAO Might have to try them in my control panel. Anyone have any experience with these?

Looking for 3 way momentary, and 2 way momentary, and 2 way maintained, and hell 3 way maintained.... All waterproof please. Any info, I'd really appreciate it. No porn links please. Thanks.

I am trying to understand the relay wiring diagram. Running 9.2mA of 120VAC across position 13 to 14 activates the coil that flips 12 & 9 (which is normally closed with 4, & 1 respectively) to be now closed with 5,&8 respectively. Is this correct? Now regarding the light which uses 12...

I wanted to build another brutus-clone, this time more along the lines of this for my brother. I have a standard brutus-clone, and the drain ball valves on the kettles are protected from direct fire by the ledge that the kegs rest upon. In this one though, I chose to have a tippy...

What burner would you recommend for boiling 50 gallons wort in a 65 gallon tank? Is 65 gallons large enough for such a boil? My buddy and I are fabricating this kettle, so it's design can be any shape/size. Is there an ideal radius/height we should be concerned about?

I'm having a difficult time finding a flanged style 50-60 Amp NEMA receptacle that is 3 Pole, 4 Wire... It can be male or female. I'm finding a Leviton style that is non-nema. Does that mean it's not waterproof, or when the plug is in it that the assembled plug and receptacle is not...

I'm looking on Ebay for a 50 Amp DPDT Relay. I'm finding a bunch of 50 Amp Magnetic Definite Contactors that look a lot cheaper. Would they be interchangeable? Thanks

I'm needing to start thinking about how to move a soon-to-be large ass piece of brewing related equipment (still brewing 5 gallons, just super-beefy). To my friggin amazement, the piece will weigh in somewhere between 700-1000 lbs. Knowing this, the welder is adding some eye-holes that could...

Yeah! Another chance to show off my lack of "street smarts" when it comes to electrical hands-on-work.... In designing a control panel, I have added up that I will need 18 DPDT mechanical relays. That seems to be a lot to stuff in a control panel. But new to me is the use of a DIN rail...

So is there going to be some metallurgic reaction using chrome plated brass in and around wort in the mash tun, or is it generally safe. I checked out John Palmers how to brew, but didn't see any mention of chrome. I mean I love hexavalent chromium in my beer. Thoughts?

If I wanted to use an XLR connector male to female inside the mash tun, are they waterproof at their connection? I was looking at one and think it might be, but I can't tell about the latching lever if that's water proof. Anyone?

Would it be a bad idea to use a mechanical dpdt relay with it's coil relayed with 120V AC, and one switch DC, and the other switch AC? Does the dc leg present a problem?
