Hello All,
I have a question about heating a tank of water. Its not really Allen Bradley specific, but i am using a ControlLogix unit...
Anyway, I'll attach a basic drawing of the layout.
I need to heat water to 65deg using an existing heat exchange. Once it is hot, then the water is diverted to a machine for cleaning.
At the moment i am using temp sensor 1 to continue the cycle until it reaches temperature.
Meanwhile Temp sensor 2 has three levels (x<80, 80<x<85, x>85) to open the proportional valve to regulate the steam to the heat exchange at three levels.
This process takes a long time, so I'm wondering if i could improve the process anywhere? Besides hardware changes.
Thankyou.
Edit: Because of the layout of the sensors etc. The water at sensor 2 reaches temperature much quicker. I was using sensor 1 to ensure the entire tank was hot enough. Maybe i just need to do some trials with sensor 2 as the process variable.
