M6 Brass NPT Screw Threaded Car In-car Temperature Sensor 5k Ohm 3950
Working principle Of The In-car Temperature Sensor
The
higher
the
interior
temperature
indicated
by
the
interior
temperature
sensor,
the
more
the
hybrid
door
moves
toward
the
colder
direction,
and
the
lower
the
temperature
of
the
air
outlet.
Anyway,
the
lower
the
interior
temperature
indicated
by
the
interior
temperature
sensor,
the
hotter
the
hybrid
door
becomes.
Moving
in
the
direction,
the
higher
the
temperature
of
the
air
outlet.
The
temperature
sensor
in
the
car
is
generally
installed
at
the
lower
end
of
the
dashboard.
It
is
a
thermistor
with
a
negative
temperature
coefficient.
The
resistance
of
the
thermistor
will
gradually
decrease
as
the
temperature
rises.
Its
function
is
to
detect
whether
the
temperature
in
the
car
reaches
the
set
value
to
control
the
work
of
the
air-conditioning
system.

Features Of The In-car Temperature Sensor
●
Application
description:
Suitable
for
automotive
internal
temperature
control
module;
●
Assembly
method:
Threaded

Dimension Of The In-car Temperature Sensor (mm)
Method of detecting temperature sensor in car
(1)
Voltage
measurement
Remove
the
air
conditioner
controller,
but
the
connector
is
not
disconnected,
turn
the
ignition
switch
to
the
"ON"
position,
use
a
multimeter
to
measure
the
voltage
between
the
controller
connection
terminals
TR
and
SG-3
(Figure
5-17),
the
measured
voltage
value
Should
decrease
with
the
increase
of
temperature,
the
voltage
should
be
1.8～2.2V
at
25℃,
and
1.2～1.6V
at
40℃.
(2)
Resistance
measurement
Remove
the
temperature
sensor
in
the
car
and
measure
the
resistance
between
terminal
1
and
terminal
2
of
the
connector.
The
resistance
should
decrease
with
the
increase
of
temperature.
At
25℃,
the
resistance
should
be
1.65～1.75kΩ,
and
at
40℃,
the
resistance
should
be
0.55～0.65kΩ.
If
it
is
not
normal,
replace
the
temperature
sensor
in
the
car.
The
in-car
temperature
sensor
is
also
called
the
indoor
temperature
sensor.
It
is
one
of
the
important
sensors
of
automatic
air
conditioning.
It
will
affect
the
temperature
of
the
air
at
the
outlet,
the
speed
of
the
blower,
the
position
of
the
intake
door,
and
the
position
of
the
mode
door.
It
is
usually
installed
in
the
suction
device
behind
the
dashboard.
