VI DESIGN Of The Disc NTC Thermistor MF57
Choice
of
the
resistances
If
the
application
is
to
measure
the
temperature
around
a
defined
point,
a
unique
nominal
resistance
can
be
chosen
(for
example,
among
standard
values
of
the
ND
range
products
presented
on
pages
20
to
24).
When
it
is
required
to
measure
the
temperature
over
selected
ranges
T1
–T2
,
T2
–T3
,
...,
the
corresponding
resistance
R1
,
R2
,
R3
,
...,
must
be
such
that
they
can
be
located
on
the
R
(T)
characteristic
of
an
existing
NTC
material
(for
example
among
standard
materials
whose
R
(T)
are
displayed
on
pages
29
to
33).
The
resistances
must
also
be
compatible
with
the
resistivity
of
the
material
and
the
dimensions
of
the
thermistor.
