Precautions Of The Enameled Wire NTC Thermistor 6.8k 3977
Welding
method:
The
metal
body
and
the
body
are
directly
welded
for
welding.
Please
do
not
use
tin
soldering
to
avoid
false
welding.
The
welding
time
is
controlled
within
3.5
seconds
Do
not
test
the
enameled
wire
thermistor
in
the
air.
The
temperature
in
the
air
varies
greatly
and
the
measurement
is
very
inaccurate.
It
often
produces
deviations
above
1-2°C.
It
must
be
measured
with
a
high-precision
constant
temperature
oil
tank.
The
tested
NTC
is
placed
in
the
constant
temperature
oil
tank.
After
that,
the
temperature
of
the
constant
temperature
bath
must
be
stabilized.
