MPn-4C Methane Gas Sensors High Sensitivity Semiconductor
Description
MPn-4C
adopts
a
multi-layer
thick
film
manufacturing
process,
which
integrates
a
heating
electrode,
a
measuring
electrode
and
a
metal
oxide
semiconductor
gas
sensitive
layer
on
an
Al2O3
ceramic
substrate,
and
encapsulates
it
in
a
metal
housing.
When
the
detected
gas
is
present
in
the
ambient
air,
the
conductivity
of
the
sensor
will
change,
and
the
higher
the
concentration
of
the
gas,
the
higher
the
conductivity
of
the
sensor.
This
change
in
conductivity
can
be
converted
into
an
output
signal
corresponding
to
the
gas
concentration
using
a
simple
circuit.
The
product
has
good
anti-interference
ability
to
common
gases
such
as
alcohol
and
acetic
acid
in
the
use
scene.
Application
It
is
widely
used
in
combustible
gas
leak
monitoring
devices,
fire/safety
detection
systems
for
home,
factory
and
commercial
use;
Flammable
gas
leak
alarm,
gas
leak
detector,
etc.
Features
High
sensitivity
to
CH4
gas
Excellent
anti-interference
ability
Excellent
stability
