Potentiometer / variable resistor.

It could be that you only require to run the motor at a fixed speed to produce your 60psi constant pressure, however, if the process is variable and it needs to tune itself. THe higher end Rockwell drives have built in PID functions that can use the 4-20mA signal from the pressure transmitter to ajust it's own speed accordingly.

I’m want to use a Allen Bradley 22-A4P2N113 Powerfex

That particular model doesnt have PID capabilities.

I would install it, an using the dial on the front, see if a 60psi constant pressure is feasible without PID control.

If it isnt, then an Allen Bradley 820 plc will be the cheapest way to introduce PID control. An the software for it is free.

Ok thanks for all the help. Appreciate it
