LOW CONSUMPTION PNEUMATIC CONTROLLER

摘要

A pneumatic controller for controlling a process advantageously reduces f luid consumption by providing a proportional adjustment to a feedback signal . The pneumatic controller comprises a pneumatic control stage, a process pr essure detector, and a feedback proportioning device. The feedback proportio ning device uses a feedback cantilever component to provide the proportional adjustment of the feedback signal, thereby reducing the fluid consumption o f the pneumatic controller.
