VEGASON 54K … 56K 13
Technical data
1) Similar to DIN 16 086, reference conditions acc. to IEC 770;
temperature 15°C … 35°C; moisture 45 % … 75 %; pressure 860 mbar … 1060 mbar.
2) The adjustment time is the time, required by the sensor, to output the correct level after a quick level
change (with max. 10 % deviation).
Accuracy 1)
(typical values under reference conditions, all statements relate to the nominal measuring
range)
Characteristics linear
Deviation in characteristics including
linearity, reproducibility and
hysteresis (determined by
limit point methods)
< 0.1 %
Linearity better than 0.05 %
Average temperature coefficient of the
zero signal 0.06 %/10 K
Resolution in general max. 1 mm
Resolution of the output signal 0.01 % or 1 mm
Characteristics 1)
(typical values under reference conditions, all statements relate to the nominal measuring
range)
Min. measuring range
(between empty and full adjustment) > 20 mm (recommended > 50 mm)
Ultrasonic frequency (at 20°C)
- VEGASON 54
30 kHz
- VEGASON 55 18 kHz
- VEGASON 56 10 kHz
Measuring intervals
- VEGASON 54
1.0 s
- VEGASON 55 1.5 s
- VEGASON 56 2.0 s
Beam angle at -3 dB emitted power
- VEGASON 54
4°
- VEGASON 55 5°
- VEGASON 56 6°
Influence of the process temperature 1.8 %/10 K, however is compensated by an
integral, dynamic temperature detection
system in the transducer
Influence of the process pressure negligible within the approved sensor pressure
range
Adjustment time 2)
- VEGASON 54 > 2 s (depending on parameter adjustment)
- VEGASON 55, 56 > 4 s (depending on parameter adjustment)
