Hi, I am new to pid and automation in general. I am hoping someone can verify if what I am planning will work.
I have a pid controller that I will be using a thermocouple as the input. It has a 0-10vdc linear output and a relay out for the second output. I am planning to use the relay output for a overtemperature warning buzzer, and the linear output will go to a sensor module which can interpret the 0-10vdc and send it to my mobile device so I can see the temperature of the oven at any time from anywhere. The oven is controlled by its own controls.
I'm not sure how this will work, though. If I only use proportional control and turn the gain to zero, will the output basically be an inverse of the rising oven temperature since it will never hit the set value (which I will set as max oven temp)?
I know there are likely better ways to do this, like with a thermocouple transmitter, but I am trying to do it with the parts that I already have.
Thanks for any input or suggestions.
