Delphi Differential Pressure Sensor The Delphi Differential Pressure Sensor, or "Delta P Sensor," provides a voltage output to an engine management system proportional to the differential pressure (∆ p) between two sources. The sensor is designed primarily for use in diesel engine applications to signal the need for regeneration of the system's particulate filter, or soot trap. Since a diesel engine produces a greater volume of particulate matter than a gasoline engine, it typically requires a trap (filter) to minimize particulate exhaust emissions. As matter produced by combustion accumulates in the particulate trap, the pressure differential across the trap increases. The Delphi Differential Pressure Sensor precisely measures the status of the matter blockage in the particulate trap and provides input to the engine management system to initiate regeneration, or a burn-off of the excess particulates in the trap. This process enables the diesel engine management system to maintain the required limit of particulate matter emissions. Delphi Differential Pressure Sensors Mounting flexibility and small size enhances system packaging requirements All silicon solid state technology for durability and reliability Temperature compensated Electro magnetic interference (EMI) protected Meets OBD II requirements for diagnostic bands Typical Applications The Delphi Differential Pressure Sensor is designed for a range of light duty diesel automotive and heavy duty diesel commercial vehicle applications. It is also suitable for other diesel systems in which filter regeneration is required, including stationary power generator applications, and solid oxide fuel cells. Availability Engineering samples will be available to qualified manufacturers in 2013. Contact Delphi for further information. www.delphi.com | © Delphi. All rights reserved. |
