Measuring range
5.2.1
Sensor features
• Beam angle (α): 11 °
• Blocking distance (BD): 0.5 m (1.6 ft)
• Maximum range for liquids: 20 m (66 ft)
• Maximum range for bulk solids: 10 m (33 ft)
5.2.2
Blocking distance
NOTICE
If the blocking distance is undershot, this may cause a device malfunction.
‣
Mount the measuring device high enough that the blocking distance is not reached at
the maximum fill level.
‣
Define the safety distance (SD).
‣
If the level enters the safety distance SD, the device generates a warning or alarm.
‣
The measuring span F may not project into the blocking distance BD. Level echoes
within the blocking distance cannot be evaluated due to the transient response of the
sensor.
