3.2 Principle of operation
The VEGADIS 81 is an external measured value indicating unit that
can also be used to adjust the sensors.
Depending on the sensor, it can be mounted up to 25 m or 50 m away
from the sensor and is directly powered by the sensor. A separate
voltage supply is not required.
If the sensor is difficult to access, it can be mounted at a more favour-
able location.
The measured value indication and the sensor adjustment are carried
out via the display and adjustment module integrated in VEGADIS 81.

and adjustment module is selected for this example.
