5 Installation
General information
The following points must be observed during installation:
• Secure the insertion sensor against pipe vibration.
• Insertion sensors must be installed without mechanical
tension (torsion, bending).
• Ensure temperature limits are not exceeded when
operating the insertion sensor.
• Avoid vacuum shocks in the piping to prevent damage to
the insertion sensor. Vacuum shocks can destroy the
insertion sensor.
• Do not remove the sealing plugs in the cable glands until
you are ready to install the electrical cable.
• The transmitter with a remote mount design must be
installed at a largely vibration-free location.
• When installing the transmitter in a control cabinet, ensure
adequate cooling is provided.
Pre-installation requirements
• Before installing a remote insertion sensor, check the cable is
of sufficient length for application/site conditions.
• Use only a single cable length. If the cable is not of sufficient
length do not extend it; replace it with new cable of sufficient
length and pot the terminal housing at the insertion sensor
end as detailed on page 16.
Installation requirements
CAUTION
• The installation conditions shown must be
observed to achieve the best operational results.
• Care must be taken when unpacking and lifting
the insertion sensor.
Fluid level
The insertion sensor pipe must always be completely full.

Extremes of temperature
Do not install the insertion sensor in a position that will expose
it to extremes of temperature (for example, direct sunlight,
frost and snow). Provide appropriate weather protection where
necessary.
