3. Special conditions for use (X conditions)
4) The instruments must be earthed via the process connection. This
is why electrically conductive sealing should be used at the process
connection. Alternatively, take other measures for grounding.
External sources of stray electric currents depend on end use
application and must be assessed by the end user.
5) Avoid handling of materials that react dangerously with the materials
used for the instrument, and substances liable to spontaneous
combustion.
6) Avoidance of vibration
Requirements for the installation point
If the line to the instrument is not adequately stable, an instrument
holder should be used for fastening. If vibrations cannot be avoided
by means of suitable installation, use instruments with liquid filling.
Protect the instruments against coarse dirt and wide fluctuations in
ambient temperature.
Permissible vibration load at the installation site
Always install the instruments in locations free from vibration. If
necessary, it is possible to isolate the instrument from the mounting
point, e.g. by installing a flexible connection line between the measuring
point and the instrument and mounting the instrument on a suitable
bracket. If this is not possible, do not exceed the following limits:
Frequency range < 150 Hz
Acceleration < 0.5 g
7) When using thermowells, they should be filled with a thermal contact
medium in order to reduce the heat transfer resistance between
the outer wall of the probe and the inner wall of the thermowell. The
working temperature of the thermal compound is -40 ... +200 °C.
8) Clean the thermometer with a moist cloth. Ensure that due to the
cleaning no electrostatic charge will be generated.
9) All accessories (e.g. thermowells or attachment components) must
be assessed in combination with the delivered instruments by the
end user. Particularly the requirements of grounding and prevention
of electrostatic charges must be considered.
