2. Safety
5. Temperature increase through compression warming
Avoid the increasing of warming due to gas-compression. In these cases it may
be necessary to throttle the rate of change of pressure or reduce the permissible
medium temperature.
6. Equipotential bonding
The instruments must be connected to the equipotential bonding of the plant via
the process connection by the end user in the end use application. Avoid use of
electric insulating sealing materials.
7. Handling of materials
Avoid exposing the instrument to any substances or ambient conditions that could
negatively affect the instrument and the materials used. Avoid handling substan-
ces that are liable to spontaneous combustion. For a list of the materials used,
see chapter 3 "Specifications". The materials of wetted parts not listed there (e.g.
Hastelloy) are noted on the dial.
8. Permissible vibration load
The instruments should always be installed in locations free from vibration. If the
line to the instrument is not adequately stable, an instrument holder should be
used for fastening.
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 pressure
gauge and mounting the instrument on a suitable bracket.
At the installation site
If vibrations cannot be avoided by means of suitable installation, instruments with
liquid filling should be used.
However, the following limit values must not be exceeded:
Frequency range: < 150 Hz
Acceleration: < 0.5 g (approx. 5 m/s
9. Cleaning
Clean the equipment with a moist cloth. Do not use other cleaning processes than
manual rubbing to prevent electrostatic charging.
