For rod and rope probes with lengths of up to 8 m, the upper blocking distance is preset
to 0.2 m on delivery. For rope probes with lengths of more than 8 m, the upper blocking
distance is preset to 2.5 % of the probe lengths.
For media DC > 7, the upper blocking distance for rod and rope probes can be reduced
to 0.1 m, if the probe is mounted flush with the wall or in a nozzle of maximum 50 mm.
Blocking distance and measuring range
At the lower end of the probe there is no blocking distance but a transition region with
reduced accuracy, see section "Maximum measured error".

Larger measurement range available on request.
2.
The indicated blocking distances are preset. At media with DC > 7, the upper blocking distance UB can
be reduced to 0.1 mm for rod and rope probes. The upper blocking distance UB can be entered manually.
Note!
!
Within the upper and lower blocking distance, a reliable measurement can not be
guaranteed.
For stilling well applications
The upper blocking distance (UB) is preset to 100 mm when the "bypass/pipe"
parameter has been selected in the "tank properties" (002) function.
Maximum measured error
Typical statements for reference conditions:
DIN EN 61298-2, percentage of the span.
Output:
sum of non-linearity, non-
repeatability and hysteresis
Offset/zero
If the reference conditions are not met, the offset/zero arising from the mounting
situation may be up to ± 12 mm. This additional offset/zero can be compensated for by
entering a correction (function "offset" (057)) during commissioning.
