ECM’s NH3CAN Module is a CAN output device for the measurement of NH3 in the exhaust of diesel and other lean burn engines. This makes the module useful for SCR system development or to compensate NOx sensors for their NH3 cross-sensitivity. 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 memory chips in their connector where calibration information is stored. This allows the sensors to be recalibrated (zero, span) in a central location and distributed to users, ensuring consistent results throughout a large test facility. PC software to set-up, control, calibrate, and view outputs and sensor parameters is included (requires CAN adapter, available). An optional pressure measurement kit is available. Three optional displays, two with programmable analog outputs, are available. These displays can be used with one or two modules.
