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.
Installation
Nominal position per EN 837-1 / 9.6.7, figure 9: 90° (
Process connection bottom or rear
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
Commissioning
During the commissioning process pressure surges must be avoided at all
costs. Open the shut-off valves slowly.
