<p>A pneumatic process controller includes a nozzle mounted on a set point lever and a flapper with a connected process lever. The set point lever pivots the nozzle about a set point and input axis in response to set point adjustment. The process lever pivots the flapper about the same axis in response to the process variable. The nozzle and set point lever are mechanically separated from the flapper and process lever. Artificial effect upon the process variable from set point adjustment is eliminated.</p>
