Description
The
KGD-ZS-321
oxygen
sensor
is
a
five-wire
planar
wide-range
oxygen
sensor.
There
is
no
need
for
a
regulating
resistor
on
its
connector.
This
type
of
sensor
does
not
require
a
reference
air
sample.
Instead,
it
uses
the
reference
pump
current
as
a
fixed
reference
source
to
compare
and
calculate
the
oxygen
content
of
the
measured
gas.
