I have collected most of the components to put together a control for an electric ladel casting pot. 50 - 60 lbs. of alloy.
My intent is to use 2-240 volt elements for quicker heat up. At a set temp. 1 element would drop off & the second 1 would maintain casting temp."k" thermocouple & ssr's will be used.
This is the control I am looking at to get the job done https://www.omega.ca/pptst_eng/CNPT_SERIES.html. 3 dc pulsed outputs.
The third out put would be used as a fail safe in case of a runaway.
My question is:will this controller do what I am want or is there something else out there?
I this is a little confusing to you,please forgive me,I have no experience with pid's.
Any suggestions welcome.
Thnx Lots
Bob
