VEGASON 51P … 53P 17
Technical data
Display of measured value (optional)
Liquid crystal display
- in the sensor
scalable output of measured value as graph and
as numerical value
- external, powered by the sensor scalable output of measured value as graph and
as numerical value, display can be separated
up to 25 m from the sensor
Accuracy 1)
(typical values under reference conditions, all information relates to the nominal measuring
range)
Characteristics linear
Deviation in characteristics including
linearity, reproducibility and
hysteresis (determined acc. to the
limit point method)
< 0.1 %
Linearity better than 0.05 %
Average temperature coefficient of the
zero signal
0.06 %/10 K
Resolution general max. 1 mm
Resolution of the output signal 0.005 % or 1 mm
Characteristics 1)
(typical values under reference conditions, all information relates to the nominal measuring
range)
Min. span between
full and empty > 20 mm (recommended > 50 mm)
Ultrasonic frequency (at 20°C)
- VEGASON 51
70 kHz
- VEGASON 52 55 kHz
- VEGASON 53 34 kHz
Meas. intervals 1.0 s
Beam angle (at –3 dB acoustic power)
- VEGASON 51
5.5°
- VEGASON 52 5.5°
- VEGASON 53 3°
Influence of the ambient temperature negligible, is compensated by a dynamic
temperature detection integrated in the
transducer. The ambient temperature error
without temperature compensation is 0.18 %/K
Influence of the process pressure negligible within the approved sensor pressures
Adjustment time 2) > 2 s (depending on the parameter adjustment)
1) Similar to DIN 16 086, reference conditions according to IEC 770, e.g.
temperature 15°C … 35°C; moisture 45 % … 75 %; pressure 860 mbar … 1060 mbar
3) The adjustment time (also actuating time, response time or adjustment period) is the time the sensor
requires to output the correct level (with max. 10% deviation) after a quick level change.
