Abstract
A pneumatic condition sensing system for reducing the consumption of air supplied by a pneumatic source, the system having a bleed type pneumatic device for bleeding air from a branch line to atmosphere to control the pressure within the branch line in response to a sensed condition, an elongated restriction for connecting the bleed type device to the pneumatic source, the elongated restriction having an air conserving flow versus pressure relationship, and a controller connected to the branch line and responsive to the pressure therein for providing a control function usable in controlling a condition.
