"Function chart" (A - max. detection or overflow protection, B - min.
detection or dry run protection).
With this DIL switch (3) you can set the switching point to liquids
having a density between 0.5 and 0.7 g/cm³ (0.018 and 0.025 lbs/
in³). With the basic setting, liquids with a density of > 0.7 g/cm³ (0.025
lbs/in³) can be detected. In liquids with lower density, you must set
the switch to > 0.5 g/cm³ (0.018 lbs/in³). The specifications for the
position of the switching point relate to water - density value 1 g/cm³
(0.036 lbs/in³). In products with a different density, the switching point
will shift in the direction of the housing or tuning fork end depending
on the density and type of installation.
Note:
Keep in mind that foams with a density > 0.45 g/cm³ (0.016 lbs/in³)
are detected by the sensor. This can cause faulty switchings particu-
lary when used as dry run protection system.
