Abstract
A closed loop pressure management system for an exhaust regeneration system is provided with a first tube capable of retaining a first fluid and extending between a proximal end and a distal end, a first fitting coupled between the distal end of the first tube and an exhaust conduit for receiving an exhaust fluid, and a pressure sensor manifold. The first fitting may include a diaphragm configured to provide a sealed interface between the first fluid of the first tube and the exhaust fluid of the exhaust conduit, and communicate the exhaust fluid pressure through the first fluid pressure. The pressure sensor manifold may include at least a first inlet coupled to the proximal end of the first tube and a pressure sensor configured to determine the exhaust fluid pressure based at least partially on the first fluid pressure at the first inlet.
