· Delphi has developed the world''s first automotive ammonia sensor. The new technology will allow direct closedloop control of the selective catalytic reduction systems used by many diesel vehicles to reduce NOx. By directly measuring tailpipe ammonia, the sensor allows the injection of urea to be optimized and ammonia emissions reduced.
The Ammonia (NH3) sensor is an exhaust sensor providing direct measurement of ammonia for Selective Catalytic Reduction (SCR) dosing control and OnBoard diagnostics. The sensor output can be used to provide feedback to the SCR system helping higher engineout NOx calibration for improved fuel economy. Features / Benefits . Enables closedloop urea closing control for optimized NOx reduction ...
· The ammonia sensor is based on a nonequilibrium electrochemical principle and outputs emf signals. The sensor performs well when tested in a diesel engine exhaust environment and has minimum cross interference with CO, HC, NO, NO 2, SO 2, H 2 O and O 2.
Ammonia sensor/transmitter designed for use in industrial refrigeration applications. The ECFXNH3 can provide a linear 4/20 mA or Modbus RS485 signal input into PLC’s or SCADA systems. Can also be used with Honeywell controllers to create a complete gas detection system that includes visual/audible notification and relay outputs to activate ventilation. COMMON OPERATIONENT RANGE …
· The Delphi Ammonia Sensor uses a unique Delphi technology to directly measure ammonia levels in the exhaust of diesel vehicles equipped with a selective catalytic reduction (SCR) after treatment system. The sensor output can be used to provide feedback to the SCR system which provides optimal reduction of NOx emissions. It can detect ammonia within a range of 0 to 100 ppm. If the sensor ...
· Delphi''s solution is to combine expertise in oxygen sensors with its materials expertise to develop a new type of ammonia sensor that is ideal for automotive applications. A new ammonia …
Delphi has developed the world’s first automotive ammonia sensor. The new technology will allow direct closedloop control of the SCR (Selective Catalytic Reduction) systems used by an increasing number of diesel vehicles to reduce NO x.. By directly measuring tailpipe ammonia, the sensor allows the injection of urea (an ammoniarich compound required by the SCR system) to be optimized and ...

The ammonia sensor has also been introduced by Iveco on their Daily van and on some of their heavyduty engines. A wider use of NH 3 sensors may still be seen in the future, if more stringent NOx emission standards are adopted, such as the (now voluntary) California NOx standard of g/bhphr. The Delphi ammonia sensor operates based on a nonequilibrium electrochemical sensing principle ...
