6. Commissioning, operation

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 tted 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, gure 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 exible 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-o valves slowly.
