Abstract

An air pressure differential sensing system includes a conduit defining an air passage through which air flows upon application of an air pressure differential across different regions of the air passage, a flap pivotally connected to the conduit, and a sensing device mounted proximate to the air passage and separate from the flap. The flap is configured to move about a pivotal axis in response to the air flowing through the air passage. The sensing device is configured to sense an angular position of the flap about the pivotal axis, the angular position of the flap being a function of the air pressure differential.
