3 Mounting
3.1 Mounting preparations, mounting strap
The mounting strap is supplied unassembled (optionally) and must be
screwed to the sensor before setup with three hexagon socket screws
M5 x 10 and spring washers. Max. torque, see chapter "
Technical
data
". Required tools: Allen wrench size 4.
There are two different variants of screwing the strap to the sensor,
see following illustration:

Fig. 2: Mounting strap for screwing to the sensor
1 For angle of inclination in steps
2 For angle of inclination, infinitely variable
Depending on the selected variant, the sensor can be rotated in the
strap:
•
Single chamber housing
– Angle of inclination in three steps 0°, 90° and 180°
– Angle of inclination 180°, infinitely variable
•
Double chamber housing
– Angle of inclination 90°, infinitely variable
– Angle of inclination in two steps 0° and 90°
3.2 Mounting instructions
Radar sensors for level measurement emit electromagnetic waves.
The polarization is the direction of the electrical component of these
waves.
The polarization direction is marked by a nose on the housing, see
following drawing:
