Delta Pressure Sensor

Last update: 12 Jul. 2024

What is a Delta Pressure Sensor?

The Delta pressure sensor, also called Differential Pressure Sensor (DPS) measures the pressure drop across the EGR system.

The delta pressure sensor manages the differential pressure across particulate filter or on the low pressure EGR (Exhaust Gas Recirculation) loop. It’s a key element to ensure the particulate filter behavior to fullfill the pollutants emission threshold allowed by more and more stringent regional regulations.
