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

transition zone.The location of the

clamps will determine the beginning

of the transition zone. The probe

length should be configured as the

length from the underside of the

flange to the top clamp. See section

“Transition Zones“ on page 2-10 for

further information on Transition

Zones.
