2 .2 Principle of operation
Area of application
VEGAWAVE S 61 is a level sensor with tuning fork
for level detection.
It is designed for industrial use in all areas of
process technology and is preferably used for bulk
solids.
Typical applications are overfill and dry run
protection. Thanks to its simple and robust
measuring system, VEGAWAVE S 61 is virtually
unaffected by the chemical and physical properties
of the bulk solid.
It functions even when exposed to strong external
vibrations or changing products.
Fault monitoring
The electronics module of VEGAWAVE S 61
monitors continuously the following criteria:
l
Correct vibrating frequency
l
Line break to the piezo drive
