3.2 Principle of operation
VEGASON 62 is an ultrasonic sensor for continuous level measure
-
ment. It is suitable for liquids and solids in virtually all industries,
particularly in the water and waste water industry.
The transducer of the ultrasonic sensor transmits short ultrasonic
pulses to the measured product. These pulses are reflected by
product surface and received back by the transducer as echoes.
The running time of the ultrasonic pulses from emission to reception
is proportional to the distance and hence the level. The determined
level is converted into an appropriate output signal and outputted as
measured value.
Power supply via the Profibus DP/PA segment coupler or VEGALOG
571 EP cards. A two-wire cable according to Profibus specification
serves as carrier of both power and digital data transmission for
multiple sensors. The instrument profile of VEGASON 62 corresponds
to profile specification version 3.0.
The backlight of the display and adjustment module is powered by the
sensor. Prerequisite is a certain level of operating voltage.
The data for power supply are specified in chapter "
Technical data
".
The optional heating requires its own operating voltage. You can find
details in the supplementary instructions manual "
Heating for display
and adjustment module
".
This function is generally not available for approved instruments.
The GSD (instrument master files) and bitmap files necessary for
planning your Profibus-DP-(PA) communication network are available
from the download section on the VEGA homepage
www.vega.com
under "
Services - Downloads - Software - Profibus
". There you can
also find the appropriate certificates. In a PDM environment, an EDD
(Electronic Device Description) is also required to enable the full
range of sensor functions (also available as a download).A CD with
the appropriate files can be ordered via e-mail under [email protected].
