Heating
NOTICE
Electronics can overheat due to elevated ambient temperature!
‣
Observe maximum permitted ambient temperature for the transmitter .
‣
Depending on the fluid temperature, take the device orientation requirements into
account .
NOTICE
Danger of overheating when heating
‣
Ensure that the temperature at the lower end of the transmitter housing does not
exceed 80 °C (176 °F).
‣
Ensure that sufficient convection takes place at the transmitter neck.
‣
Ensure that a sufficiently large area of the transmitter neck remains exposed. The
uncovered part serves as a radiator and protects the electronics from overheating and
excessive cooling.
‣
When using in potentially explosive atmospheres, observe the information in the
device-specific Ex documentation. For detailed information on the temperature tables,
see the separate document entitled "Safety Instructions" (XA) for the device.
Heating options
If a fluid requires that no heat loss should occur at the sensor, users can avail of the
following heating options:
• Electrical heating, e.g. with electric band heaters
• Via pipes carrying hot water or steam
• Via heating jackets
Vibrations
The high oscillation frequency of the measuring tubes ensures that the correct operation of
the measuring system is not influenced by plant vibrations.

WARNING
Danger from medium escaping!
Medium escaping under pressure can cause injury or material damage.
‣
Take precautions to prevent danger to persons and damage if the rupture disk is
actuated.
‣
Observe information on the rupture disk sticker.
‣
Make sure that the function and operation of the rupture disk is not impeded through
the installation of the device.
‣
Do not use a heating jacket.
‣
Do not remove or damage the rupture disk.
The position of the rupture disk is indicated on a sticker beside it.
