Dew Point Detection

For the dew point detection of the NOX sensor, the temperature in the exhaust pipe at the catalyst outlet is used, which is measured by the NOX monitor to monitor the exhaust gas temperature (see section Exhaust Gas Temperature Monitoring). The dew point detection threshold is firmly predefined in the NOX monitor.

For engines with two catalytic converters in split exhaust gas lines, the exhaust gas temperature at the catalyst outlet must be measured in both exhaust gas lines for NOX sensor dew point detection.

The status of the dew point detection is displayed in the NOX Monitoring view of the EasyNOₓ (see section Overview).
