Hi Jason,
Have a 89s52 running 3 term PID control, controls 1 or 2 kW heater bands via 16amp pwm relay. Nice one! :-) test results are excellent, Well, as long at those results validate that it meets the relevant compliance standards along with performance expectations of the 'target market'.. but were do I go from here? In addition to satements already made, I would say given the above you have three options: 1.) Integrate your circuit into an existing product i.e. adding a thermostatic control circuit to a consumer electric heater. Most difficult option to take IMO, since most heater manufacturers would probably have their own designs that they can (and do) call upon. 2.) Make a standalone product for say, industrial use (which I presume is what you're trying to do?). In that case, I would suggest also adding a 'cooling' control output to your design (along with appropriate firmware) and replace both relays with beefy, arc-free SSRs http://www.crydom.com or similar. Suggest that you research existing 'current-marketplace' designs for some additional guidance. 3.) Perhaps one could also ask: Ok, now that I have created this 'heater controller' design, what other (single-loop) elements could I control with it? i.e. valve/solenoid positioner, flow/level control, automotive cruise control etc. etc. Valentin |
