Function and features
Measuring range
Offset
• The sensor detects the level of media in tanks within the active
zone,
• shows the current level on its display
• and generates 2 output signals according to the set output con-
figuration.
Switching function
(can be selected for each
output separately)
L = probe length
A = active zone/ measuring range
I = inactive zone
min = lowest measured value
max = highest measured value
OFS = offset
*With offset > 0 the OFS value is added to these values.
The area between the bottom of the tank and the lower face of the
measuring probe can be entered as offset value. Thus the display and
the switch points refer to the real tank level.
