SCR Urea pressure sensor
Application Area
Exhaust Gas After-Treatment system for Commercial Vehicles
The urea pressure sensor is a MEMS pressure sensor based on medium isolation technology, which achieves complete medium isolation through vacuum oil filling technology, and meets the requirements of use in corrosive environments. The urea pressure sensor feeds back the detected pressure signal of the urea solution to the ECU, and adjusts the injection pressure of the urea solution in real time according to the fuel injection volume demand, so that the nitrogen oxides in the vehicle exhaust and the urea solution are neutralized and reacted, and the pollution of nitrogen oxides on the atmospheric environment is eliminated.
