3. Technical data ... 6. Repairs
Permissible vibratory stress at the mounting location
T As a matter of principle the instruments should only be mounted at locations
without vibratory stresses
T Where required, a decoupling from the mounting location can be achieved
e.g. by a flexible connecting line from the measuring point to the pressure
gauge and mounting via a measuring instrument bracket.
T If this is not possible, the following limits must not be exceeded:
Dry gauges: Frequency range < 150 Hz
(Model 732) Acceleration < 0.7 g (7 m/s
Liquid-filled gauges: Frequency range < 150 Hz
(Model 733) Acceleration < 4 g (40 m/s
The liquid filling has to be checked on a regular basis.
The liquid level must not drop below 75% of the gauge diameter.

4. Commissioning

During the commissioning process pressure peaks must be absolutely avoided.
Open the shut-off valves slowly.

5. Maintenance and servicing / cleaning

The instruments require no maintenance or servicing.
The indicator should be checked once or twice every 12 months.
The instrument must be disconnected from the process to check with a
pressure testing device.
The instruments should be cleaned with a damp cloth moistened with soap
solution.

6. Repairs

Repairs are to be only carried out by the manufacturer or appropriately trained
personnel.
