Note for critical applications
Critical application
Restrictions
Solution
Inhomogeneous tempera-
ture in the tank
Increased measurement inaccuracy
Ensure uniform temperature distribution in the
tank.
Changing the medium
When the tank is filled for the first time, in
-
creased measurement inaccuracy at the end of
the probe within 100 mm
Fill the tank up to a level over 100 mm.
Deposits
Deposits can be wrongly detected as the level
Increased measurement inaccuracy around the
deposit
Clean the probe, remove the deposit.
Full tank and tempera-
ture changes at the same
time
Increased inaccuracy within the upper 100 mm
when emptying the tank
Adapt the application so that the level does not
need to be accurately controlled in the upper
100 mm. Or avoid big temperature changes if
the tank is full.
Empty tank (probe is not
in contact with medium)
and temperature changes
at the same time
A low level (up to 50 mm) is measured in an
empty tank if the tank is heated but the probe
is not in contact with the medium
Only heat the medium if the probe is in contact
with it. Do not perform any critical control oper-
ations based on the sensor's empty signal.
