The
Richards Double Tube Thermocouple Assemblies are designed for severe service applications
and
molten glass
furnaces'
The double tube
assemblies
with
a
metal outer tube are for applications where
mechanical
damage and thermal shock to the
ther-
mocouple 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.
