  • Low Consumption Pneumatic Controller
    Publication number: 20080078448
    Abstract: A pneumatic controller for controlling a process advantageously reduces fluid consumption by providing a proportional adjustment to a feedback signal. The pneumatic controller comprises a pneumatic control stage, a process pressure detector, and a feedback proportioning device. The feedback proportioning device uses a feedback cantilever component to provide the proportional adjustment of the feedback signal, thereby reducing the fluid consumption of the pneumatic controller.

  • Low Consumption Pneumatic Controller
    Publication number: 20080078449
    Abstract: A pneumatic controller for controlling a process advantageously reduces fluid consumption by providing a proportional adjustment to a feedback signal. The pneumatic controller comprises a pneumatic control stage such as a relay, a process pressure detector, and a rack-and-pinion feedback assembly. The a rack-and-pinion feedback assembly provides the proportional adjustment of the feedback signal, thereby reducing the fluid consumption of the pneumatic controller.
