Methods to Prevent & Identify
Cross-sensitive Responses
Cross-sensitive Responses
·Identify
cross sensitivity through the
calibration procedure.
·Maintain
Filters (scrubbers) - remove before depleted (i.e. NOx beads before the CO sensor)
·External
filters – replace beads when color changes
·Internal
filters - remove interfering
gases inside the sensor
·Electronically
cross compensate by measurement
