Does anyone have any good leads on these digital sensors in the photo to control each tank independently of the others? Separately, if you have a photo of your box, or any other box, I’d like to see that. Appreciate it![ATTACH]64169[/ATTACH]

It controls the fermentation tanks as well.

We have control boxes much like the first image. We use Fuji PXR/PZR PID controllers and have never had a problem with them aside from two burned out output relays--which are fairly easy to replace--in over twenty years.Timm Turrentine

Agreed with Timm
If you want to keep it discreet and simple, the Fuji PXR/PXW or the current equivalent are hard to beat. Reliable, cost effective, accurate, easy to program. Also had great luck overseas with Selec brand and Autonics brand. You don't need rocket science here. If you buy reliable equipment, you don't need midnight notifications.Phillip Kelm--Palau Brewing Company Manager--

PID Control Panels

You'll need to decide:
1.What type of temp sensors you want to go with and they should be able to mate correctly with your thermowells. You have to buy your PIDs with the feature set you need for all your input and output choices.
2.What Voltage your glycol solenoids are going to utilize. [We use 24VAC, and 24VAC or 24 VDC is advised over running line voltage in the plant to those points.]
To build one of those boxes cleanly you need things like terminal strips and wireways as there are a lot of parallel connections inside and it can get busy real quick.
You have to power the controls themselves, and then if you are using low voltage on the servos, you need a Transformer or PSU that is rated to carry the total load it will see plus some headroom. It also needs overload protection, and a master power switch is a good idea for the entire panel. A Filter or power conditioner ahead of the PIDs is a good idea. A water tight junction box on the wall can easily serve 2 vessels. From each of those points you will have sensor and control leads. I keep the sensor wires in separate conduit from the servo wires.
A Bigger box is almost always better. They can fill up quick. Give yourself extra room to work inside and keep the wiring clean as possible.
Its about impossible to upload photo files to this forum due to everything having to be downsized from its original format.I have assembly photos on email if needed.
This applies if you are building one up yourself.Warren Turner
