The torque depends on the seal used. Connecting the gauge using a clamp
socket or a union nut is recommended, so that it is easier to orientate the
gauge correctly. When a blow-out device is fitted to a pressure gauge, it
must be protected against being blocked by debris and dirt.

In order to ensure that pressure can be safely and reliably vented
■
through the case back, a distance of at least 25 mm must be left free
behind the case!
In order to avoid any additional heating, the instruments must not be
■
exposed to direct solar irradiation while in operation!
Permissible vibration load at the installation site
The instruments should always be installed in locations free from
■
vibration
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
