Abstract
A demand system is disclosed for controlling the output airflow from a pneumatic source in response to changes in airflow demand. The source includes a pressure sensitive bypass mechanism in fluid communication with a discharge manifold to divert unwanted airflow and a linear electronic limiter with a limiter signal input to control the pneumatic source and proportionally adjust output airflow into the discharge manifold. The demand system includes an airflow detector operative to produce a linear output signal proportional to the airflow through the bypass mechanism and a controller. The controller includes an input connected to the airflow detector and an output connected to the electronic limiter input and operative, as the airflow detector senses airflow through the bypass mechanism, to produce a linear output signal representative of the airflow to the limiter for altering the pneumatic source output.
