Epic fail.. that is what I meant by absence of el. knowledge
I would like to make project first and then go with realization, this way I"ll make between-steps in build-up and divide some costs which is always nice.
At 1st stage it will probably be two-tier setup with one pump which will ensure outflow in MLT-BK direction, and serve RIMS.
Since Hot Liquor Tank is 13 gallons plastic bucket (I am not going to drill it until I get same size keggle on which I will solder thread couple for sensor- as final solution), it will have RTD probe inserted from top in hot water, maybe simple design like Cat22 did (thermowell is just a section of copper pipe capped on the bottom, and it is suspended vertically in HLT), in this case I could go with DIY RTD sensor version (5 pieces for $10 shipped) like PaulHilgeman did:
Since I"ll need RTD with NPT thread later in business I am closer to Auberins solution.
That probe will be for RIMS and dis-connectable probe will be threaded into HLT... we"ll see..
I already have 2kw heater for HLT but I need another 2kw to fire up 10 gallons of water in HLT.
Is PID able to control 2 heat unit?
There will be 2 SSR with heatsinks, and PID would fire both elements at the time.. It would be great if I could wire them so I can choose which one to run, or to fire both.. hope I"ll find some schematics for that.
