Ok I've now completed the trials of the system, I'll post the temperature logs etc up on a blog once I figure out how to do it. For those who are interested: - I used a 23litre corny Keg as a fermenter. It sits inside a normal 30lt plastic fermenter with the gap filled with water. The...

Hi passedpawn, yeah autotune makes some assumptions though like the system is largely linear, which a fridge on a thermostat, and a water bath heater on a PID generally isnt. But yes this will work and along with a bit of fine tuning will work. The key that I've found is the fact that you run...

I wont get into how PID actually works, there's plenty of other material for that. Further PID is not $1000? It's not even really a physical thing, it's a software process in a stand-alone controller, a PLC or a DCS. Even an arduino can do it. One of the main problems with temperature control...

Hi All, I'm new to this forum, I've spend several years working in process control in the Oil/Gas industry here in OZ. I've developed a kit which is simply: -PID + SSR enclosure -Pt100 (not thermocouple) -400mm stainless thermocouple & grommet -Water Bath -Heater -USB temperature...
