VEGAPULS Air 41 • Autarkic device with measured value transmission via radio technology

64808-EN-210426

Fault description

Cause

Rectification

Measured value jumps to-

wards 100 %

Level

time

Due to the process, the amplitude of the

product echo decreases
A false signal suppression was not car-

ried out

Carry out a false signal suppression

Amplitude or position of a false signal

has changed (e.g. condensation, build-

up); false signal suppression no longer

matches actual conditions

Determine the reason for the changed

false signals, carry out false signal sup-

pression, e.g. with condensation.

Bulk solids: Measurement error during filling

Fault description

Cause

Rectification

Measured value jumps to-

wards 0 % during filling

Level

time

The level echo cannot be distinguished

from the false signal at a false signal po-

sition (jumps to multiple echo)

Remove/reduce false signal: minimize

interfering installations by changing the

polarization direction
Chose a more suitable installation po-

sition

Transverse reflection from an extraction

funnel, amplitude of the transverse re-

flection larger than the level echo

Direct sensor to the opposite fun-

nel wall, avoid crossing with the filling

stream

Measured value fluctuates

around 10 … 20 %

Level

time

Various echoes from an uneven medi-

um surface, e.g. a material cone

Check parameter "Material Type" and

adapt, if necessary
Optimize installation position and sen-

sor orientation

Reflections from the medium surface

via the vessel wall (deflection)

Select a more suitable installation po-

sition, optimize sensor orientation, e.g.

with a swivelling holder

Measured value jumps spo-

radically to 100 % during

filling

Leve

time

Changing condensation or contamina-

tion on the antenna

Carry out a false signal suppression

or increase false signal suppression

with condensation/contamination in the

close range by editing

Bulk solids: Measurement error during emptying

Fault description

Cause

Rectification

Measured value remains un-

changed in the close range

during emptying

Level

time

False signal greater than level echo or

level echo too small

Eliminate false signals in the close

range. Check: Antenna must protrude

out of the nozzle
Remove contamination on the antenna
Minimize interfering installations in the

close range by changing the polariza-

tion direction
After eliminating the false signals, the

false signal suppression must be de-

leted. Carry out a new false signal

suppression
