Selective catalytic reduction sensor

  • 04-Nov-2011 08:19 EDT

Gentech’s selective catalytic reduction (SCR) sensor is designed to detect the presence of and measure the level and temperature of AdBlue, the diesel emission fluid used in exhaust aftertreatment to reduce NOx emissions. The SCR system relies on the injection of an aqueous urea solution (AUS32) into the exhaust stream to facilitate the reduction of NOx emissions. The height and length of these fully customizable, universal sensors can be modified to accommodate tank geometry. They are matched to the customer application by means of level and temperature outputs compatible with Cummins, Detroit Diesel, and other dosing systems. Thermal capability of the heater coils (necessary to keep the AdBlue from freezing at low temperatures) is tailored to suit the vehicle working climates, and the heater coil geometry is matched to the tank size and shape.
