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.
