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. A pressure switch may be disposed in fluid communication with the first fluid path and the second fluid path such that the first fluid path and the second fluid path pass through the pressure switch.
