About this deal

As the most basic form of automated temperature control, on/off devices often incorporate latching relay switches, which must be manually reset after they reach a specified shutoff temperature

In 1922, Nicolas Minorsky made a real breakthrough towards what we now recognise as true PID control. Minorsky's observations and mathematical treatment would eventually evolve to give us the electronic industrial control mechanisms widely used as PID systems today. I opted to build my own controller to run a single 220/240v 5500w heating element in my boiler. After running this controller several times now, I am very happy with how it works and feel it’s worthy of sharing with you. This should be especially helpful for people who are considering building their own controller since I have all the parts listed and am including some basic instructions.MtRainier wrote:The voltage of the output doesn’t change. It’s 240VAC all the time, so the meter doesn’t need to be after the controller to measure it. The power controller chops up the sine wave so that you get less than the full currrent going through the element, but you are still running it at 240VAC, you are just missing part of each cycle. In these formulas "t" is measured in seconds, "R"is measured in ohms and "C" is measured in Farads.

Next, you’ll need to divide this BTU output by 3.41 to get the wattage of your towel rail – this is the number that you’ll use to decide which power element you need – try to find the closest match (10% above or below is best). So, a 300w towel rail element would be perfect for a 320w towel rail. Or, a 600w element would work great with a 580w towel rail… you get the gist! It is possible to install the temperature probe from the controller in the column thermometer location, but it is best to install it in the boiler location. This dial face for the above controller. This wasn't needed but i thought it added a finished touch to the enclosure while also giving me a visual point of reference on for the potentiometer that controls the power output.

When running a still with a digital controller it is best to run the controller in manual mode. Read the directions on switching the controller to manual mode in this article. How to Use a Digital PID Controller to Run a StillWhen it comes to selecting a towel rail element, safety should be your top priority. We know that feeling safe and secure is essential for us all – so let’s take a look at some of the key features you should consider when choosing a model for your home. I used this circuit breaker as the power switch. I could have used a simple 220v 30a wall type switch but I wanted something a bit more robust. This is a rail mount circuit breaker which allowed me to firmly mount the breaker switch in my controller: In these formulas “t” is measured in seconds, “R” is measured in ohms and “C” is measured in Farads.

Ceramic elements boast a high energy efficiency by converting around 96% of the input power to heat to extremely high proportions. They are suitable for: PID devices are typically shipped by their manufacturers with default settings programmed for the proportional, integral and derivative. Operators installing and using any type of PID instrument must first calibrate the device, making sure it is properly programmed and adjusted to suit the specific needs of the industrial process in question. This also includes ensuring that the environmental parameters that it is required to operate between are appropriate for the potential variables occurring within that process. Until this process has been completed, the PID controller cannot be left to automatically handle its assigned workload.Before move on, a reminder: Brewing beer is legal in every US state. However, distilling alcohol is illegal without a federal fuel alcohol or distilled spirit plant permit as well as relevant state permits. Our distillation equipment is designed for legal uses only and the information in this article is for educational purposes only. Please read our complete legal summary for more information on the legalities of distillation. The wiring diagram is right in that you are putting it in parallel with the load. You should do that. Just do it before the controller which modifies the sine wave. The diagram doesn’t know that you will be using it for something messing with the wave. The induction coil will measure the load current just fine. It is also easy to retrofit our heating element adapter to a copper still with a copper still heating element adapter kit. The copper adapter kit includes everything you need to add a heating element to a copper still. I've used my digital induction meter many times so far and nothing has happened, but I could believe there would be long term issues. I put a big honking computer fan blowing into the controller case with air holes drilled in the case to keep everything cool, so maybe that helps. I also keep the controller box well away from where any alcohol vapor could be coming out even though that shouldn't happen unless I forgot to turn on the condenser cooling or something. I will note that I am not an electrician but the wiring is very straight forward. I did a lot of reading here before taking on this endeavor which insured my success. Since 220v is essentially a pair of 110v hots, I was able to wire up a 220v outlet in my garage to run this thing by adding a dual pole 30amp breaker to my sub panel and then an outlet box with a L6-30R receptacle.
