Ammonia Analyser - Automotive & Industrial

Unlike all other ceramic NOX sensor systems, the Model 5240 eliminates the cross-interference of NH3 in the NOX measurement and hence provides separate NOX and NH3 readings. By doing this, diesel engine SCR systems can be properly developed and tested since you now know whether an increased signal output is due to NOX ( urea dosing too low) or NH3 ( urea dosing too high).

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

09/02/2018· Turns out that MQ137 sensor can measure NH3, C2H6O and even CO. But, here I am interested only in the values of NH3. However you can use the same method to calculate ppm for any sensor you like. This graph is the only source for us to find the value of ppm and if we could somehow calculate the ration of Rs/Ro (X-axis) we can use this graph to find the value of ppm (Y-axis). To find …

Ammonia Sensor for Closed-Loop SCR Control

sensor compensation through air humidity only or even calibration based on climate zone where the resultant inaccuracy is tolerated by the control system. To have highest accuracy of the NH 3 sensor, reliable inputs of air humidity and exhaust A/F ratio will be needed for H2O-O2 correction. NO 2 – As a strong oxidizing agent, NO 2 interferes

We report improved sensitivity to NO, NO2 and NH3 gas with specially-designed AlGaN/GaN high electron mobility transistors (HEMT) that are suitable for operation in the harsh environment of diesel exhaust systems. The gate of the HEMT device is functionalized using a Pt catalyst for gas detection. We found that the performance of the sensors is enhanced at a temperature of 600 °C, and the ...
