Permissible vibration load at the installation site
■
The instruments should always be installed in locations free from
vibration.
■
If the pipe to the gauge is not rigid enough for a vibration-free
installation, the gauge should be mounted by means of mounting
devices for surface or pipe mounting, and, if necessary, with a capillary.
■
If necessary, it is possible to isolate the instrument from the mounting
point by installing a flexible connection line between the measuring
point and the pressure gauge and mounting the instrument on a suitable
bracket.
■
If this is not possible, the following limit values must not be exceeded:
Frequency range < 150 Hz
Acceleration < 0.5 g (5 m/s
2
)
Commissioning
During the commissioning process pressure surges must be avoided at all
costs. Open the shut-off valves slowly.
8. Maintenance and cleaning
8.1 Maintenance
■
The instruments are maintenance-free.
■
The indicator and switching function should be checked once or twice
every year. The gauge must be disconnected from the process to check
with a pressure testing device.
■
Repairs are only to be carried out by the manufacturer or appropriately
trained skilled personnel.
