Hi Guys
I have been asked to set up 3 evaporative condenser fan motors on a single
pressure transducer.
I want to stage the drives on and off according to what the pressure will
be and maintain an Ideal pressure level.
I think I can do this with a 4-20 MA retransmitter?
Or, can the 3 drives share a PID loop having 1 transducer?
Or, should I use 3 transducers on a common header?
I have never done the PID thing before and I would like to set it up and
run it on the bench to make sure it works.
Thanks in advance
