The
Richards Double Tube Thermocouple
Assemblies
are designed
for
severe service
applications. The
double
tube
assem-
blies with a metal outer tube are for applications
where
mechanical damage and thermal shock to the
thermocouple
is
a
problem.
The
double tube assemblies, which have
a
Silicon Carbide outer tube, are for applications where thermal shock and flame contact is
a
problem.
Double ceramic tube assemblies are for extra protection against corrosive
atmospheres.
We offer many other combinations
of double tubes, which we
could
not list
in
this catalog due to
space
limitations.
Richards double
tube
assemblies
can
be
made
from
any
type of
metal
or
ceramic
tube, which
is available.
