Abstract
A pneumatic signal conditioning device may have a first fluid path and a second fluid path. The first fluid path includes a first inlet and a first outlet, and is configured such that the first outlet provides a first conditioned signal representing a pressure at the first inlet. Similarly, the second fluid path is configured such that the second outlet provides a second conditioned signal representing a pressure at the second inlet.
