I am at a loss...
I have a pasteurizing system that i need to control product temperature with the speed of the product pump. I currently have a compact logix PLC, PF525 vfd, and a temperature sensor checking the product temperature. I have tried a PID, but the pump wants to speed up to get up to temp. I need the pump to slow down so that stays in the heat exchanger longer so then the product will heat up.
Any suggestions on how i can make the pump slow down automatically? Is a PID the best solution?
All help is much appreciated!!
