SI5012

5 Installation

CAUTION

During installation or in case of mechanical failure, high pressure or hot media can leak
from the system.

Risk of injury caused by pressure or burns.

Ensure that the system is free of pressure during installation.

Ensure that no media can leak at the mounting location during installation.

5.1 Installation position

5.1.1 Immersion depth

≥

12 mm

Fig. 5: Immersion depth

•

The sensor tip must be completely surrounded by the medium.

•

Recommended immersion depths: minimum 12 mm.

5.1.2 Recommended mounting position

Fig. 6: Recommended mounting position

•

For horizontal pipes: mounting from the side.

•

For vertical pipes: mounting in the rising pipe.

5.1.3 Conditionally possible installation position

Fig. 7: Conditionally possible installation position

•

For horizontal pipes, if the pipe is free from build-up: mounting from below.

•

For horizontal pipes, if the pipe is completely filled with medium: mounting from the top.
