VEGASON 54P … 56P 5
Product description
Output signal
The level-proportional Profibus PA measure-
ment signal is processed and outputted
completely digitally. Digital processing of the
measurement signal ensures an accuracy
which could be never reached by an ana-
logue measurement signal, as the digital
signal is always transmitted error-free right
up to the last decimal position. Varying
resistances or tiny leakage currents do not
influence the accuracy of digital technology.
The digital signal is always clear and unam-
biguous.
The digital signal, giving a faithful representa-
tion of the adjusted measuring range of the
sensor, can be modified by various param-
eter settings.
Measured value display
As an option, the series 50 ultrasonic sensors
can be equipped with an indicating instru-
ment for direct, local level survey. The indi-
cating instrument shows the precise level by
means of the analogue bar graph and the
digital number value. In addition to the indica-
tion in the sensor, you can have the level
displayed with the VEGADIS 50 external
indicating instrument at a distance of up to 25
m from the sensor. The external measured
value display operates, like the integrated
display, independently of the PA output signal
and can be modified through individual pa-
rameter settings.
1.2 Application features
