Figure 8-9
Figure 8-9 shows the smaller stainless
steel clamp being screwed onto the
other end of the heat shrinks for safe
tightening of heat shrink and cable.
The clamp is needed for durable
sealing.
Figure 8-10
Figure 8-10 shows the completed
cable to sensor transition. The
sensitive face of the sensor is pointing
downwards; no magnetic holder and
earth connection wire is shown.

Sealing the transition of a cable-in-a-tube to sensor against
12 bar peak pressure
Within for instance a ship's tank it is assumed that for protection of permanently installed cables
from mechanical damage and from oil, the coaxial cable run through a sealed tube to ISAS3. At
ISAS3 side the tube must end in a flexible part which is sealed to ISAS3 with a heat shrink of
appropriate diameter. RW200-E heat shrinks are available with inner diameters (before
shrinking) of 15.9 mm, 19.1 mm, 22.2 mm and 25.4 mm.
If the inner diameter of the flexible tube is bigger than 11.0 to 11.5 mm (the outer diameter of
the connector adapter), a heat shrink hose might be needed which is directly fitted onto the
connector adapter.
For a long term sealing, clamps must be used as shown in the chapter before. These are
available for the following diameter ranges: 12.2 to 17 mm, 14 to 19 mm, 15.5 to 21 mm, and
17.3 to 22 mm. Up to Ø 22 mm tubes and clamps (before clamping) are possible.
