Did you take the PE exam in Controls? Or did you do EE? I’m asking because I got my degree in ChE, but I now work with DCS. I have my EIT, but I was hesitant to go for a PE in Chem E because I don’t use any of it in my current job.
“I have my EIT, but I was hesitant to go for a PE in Chem E because I don’t use any of it in my current job.”
Just take a refresher course and sit for the exam. It’s easy.
My license is EE. Not all states recognize the Controls discipline, two of which are New Jersey and Alaska. Since you are doing work with DCS’s, you are working with process controls, thus applicable to chemical engineering.
I have done process modeling, for the purpose of validating control schemes. When you look at the math involved, it is not much of a leap from being able to do an electrical circuit analysis to being able to do a heat and material balance. This is why everything is covered on the EIT. And when you look at control systems, it overlaps every other engineering discipline except for civil engineering.
