7.6 Installation of the unit with single probe
Before installing and removing the unit: Make sure that no pressure is
applied to the system and that there is no medium in the tank that could
leak� Also always take into account the potential dangers related to extreme
machine and medium temperatures�
For installation in closed metal tanks, the tank lid serves as a launching plate R
(fig� 7-10, fig� 7-12) and (→ 12.1)�
Options are as follows:
• Installation to G¾ process connection directly in the tank lid (→ 7.6.1)
• Installation in the tank lid using a flange plate (e�g� for tanks with thin walls) (→
7�6�2)
During installation of the process connection on the tank lid observe the
subsequent orientation of the housing (display orientation, cable outlet)�
The sensor housing cannot be rotated with respect to the internal thread!
Subsequent alignment of the sensor housing is therefore not possible�
Furthermore, installation in open tanks (→ 7.6.3) and plastic tanks
is possible(→ 7.6.4)�
7.6.1 Installation to G¾ process connection directly in the tank lid
The elastomer seal on the sensor is used as
process seal� The supplied flat seal can be used
to smooth out unevenness on the tank lid process
connection�
The upper sealing area on the process connection
must be flush with the tapped hole�
► Slightly grease the sensor thread with a
suitable paste�
► Insert the unit into the process connection�
► Tighten it using a spanner� Tightening torque:
35 Nm
