NOx Sensors - DieselNet

The sensor uses two or three electrochemical cells in adjacent chambers. The first cell electrochemically pumps O 2 out of the sample so it does not interfere with the NOx measurement in the second cell. The need to remove O 2 allows this type of NOx sensor to serve a dual purpose; it can also detect exhaust O 2 level. Figure 1. Schematic ...

ECM - NH3CAN

NH3CAN uses a ceramic sensor that is mounted in the exhaust of the engine and communicates NH3 via its CAN port. Although designed as a measurement tool, the NH3CAN can be easily integrated into an engine or aftertreatment control strategy. The CAN node identification can be programmed by the user allowing multiple NH3 modules on the same bus. NH3 sensors used with the module have …

C2N monolayer as NH3 and NO sensors: A DFT study ...

01/09/2019· NH3 and NO are some of the most prominent toxic gases which mainly come from chemical and biological processes and are harmful to human and animal lives. For example, the standard for NO gases is given as 25 ppm for 8 h of work shift and 50 ppm for NH 3 by Occupational Safety and Health Administration (OSHA). Levels over these limits result in severe breathing difficulties, skin, eyes, nose …

Ammonia Analyser

With six analogue outputs, CAN, and USB communication, the NOX/NH3 5240 can be integrated into any data acquisition system. To simplify in-vehicle use, the NOX/NH3 5240 can be turned on and off with a signal from the vehicle's ignition switch. This feature along with the analyser's CAN communication capability makes it possible to integrate the NOX/NH3 5240 into the loop of a real-time emissions …

The naked-eye NH3 sensor based on fluorinated graphene ...

Here, we find that fluorinated graphene (FG) shows an obvious color change (from white to dark yellow) in the presence of NH3 which can be observed directly by the naked eye. PL measurement shows that the sensitivity of color change can reach a high value of ca. % ppm−1. The density functional theory calculations reveal that the F atoms on FG increase the adsorption ability and charge ...
