A device comprised of a pressure transducer, signal conditioning circuitry, and associated hardware, designed to measure the resistance a fluid or gas encounters while flowing through a system. For example, in an internal combustion engine, such a system enables monitoring the obstruction present within the exhaust system, often caused by particulate filter accumulation.
Understanding and accurately measuring this resistance is critical for optimizing system performance, preventing damage, and ensuring regulatory compliance. Monitoring facilitates proactive maintenance, potentially averting costly repairs or system failures. Historically, rudimentary methods were used to assess the presence of an obstruction; modern devices offer precise, real-time data, allowing for more sophisticated control strategies.
