Rosemount 3300 Series
Coaxial probe.
The Coaxial probe can be guided by
a tube welded on the tank bottom.
Tubes are customer supplied. Make
sure that the probe can move freely
in order to handle thermal expansion.
Rigid Twin Lead probe.
The Rigid Twin Lead probe can be
secured to the tank wall by cutting
the center rod and putting a fixture at
the end of the outer rod.
The fixture is customer supplied.
Make sure the probe is only guided
and not fastened in the fixture to be
able to move freely for thermal
expansion.
Flexible Single Lead probe.
The probe rope itself can be used for
anchoring. Pull the probe rope
through a suitable anchoring point,
e.g. a welded eye and fasten it with
two clamps.
The length of the loop will add to the
dead zone.The location of the
clamps will determine the beginning
of the dead zone. The probe length
should be configured as the length
from the underside of the flange to
the top clamp. See section “Dead
Zones“ on page 2-7 for further
information on Dead Zones.
