The NOxCAN module is a universal and highly intelligent NOx/Lambda/O2 measurement module. This module is installed on the engine exhaust pipe through a direct insertion NTK ceramic NOx sensor to measure NOx/Lambda/O2. All sensor parameters are output through CAN. Although designed as a measurement tool, NOxCAN can be integrated into engine or aftertreatment system control. Users can configure CAN to enable the use of multiple modules on the same bus. H: The fuel composition ratios of C, O: C, N: C, and H2 can be set. The sensor used with the NOxCAN module has a storage chip in its connector to store calibration data, so users can perform zero or span calibration on the sensor. PC software is used to set, control, calibrate, browse output and sensor parameters (requires CAN adapter, not included in NOxCAN module). Optional display head with analog output, used to connect one or two NOxCAN modules.
