Melt bolt
thermocouples are
used
to measure plastic
melt
temperatures
as
the material moves
down
the barrels
in
extruders
and
injection molding
equipment.
The element and bolt are
both
constructed from 304 stainless
steel.
The element is a
MgO
type with
a
grounded
junction. The extension and
tip
lengths
can be
specified
for your
application.
Melt bolts can
be
ordered with
1/2"-20
N.

lengths
of
3", 4", 6",
and 9". Melt
bolts
can be made in
many
configurations, which are

lVelt bolt thermocouples
are
machined from solid
3A4
stainless steel bar stock for corrosion
resistance.
The elements are constructed with MgO
i
nsulation
for
maxi
mum temperature resistance.
The
tips are 3/16"
in
diameter
and
also
made from
304 stainless steel.
A
grounded junction
is
standard
for
a
rapid temperature response time.
All
melt
