sensing
element
integrates
a
heater
within
the
chip
to
maintain
consistent
measurement
accuracy
over
extended
periods
of
use.

Application
This
nitrogen
oxide
sensor
chip
utilizes
electrochemical
principles
to
accurately
measure
NOx
content
in
vehicle
exhaust
by
detecting
electric
current
magnitude.
Designed
primarily
for
commercial
vehicle
nitrogen
oxide
sensors,
it
provides
reliable
emissions
monitoring
for
compliance
with
environmental
regulations.
