Thermocouple
Wire
-
Bare
When selecting
bare
thermocouple wire, keep
in mind
that a
larger gauge
wire will
give
a
longer
service
life
and a higher
max-
imum
temperature
limit.
A
smaller
gauge wire
will
give
you a lower
maximum
temperature
limit
and
shorter
service
life, but
will
have
a faster
response
time.
Standard limits of error are provided as specified
by
the part numbers shown
below.
Special limits can
be
specified
by doubling
the type letter
in
the
part number.
