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,VEGAVIB 62 is
virtually unaffected by the chemical and physical properties of
the bulk solid.
It functions even when exposed to strong external vibration or
changing products.
Solid detection in water
IfVEGAVIB 62 was ordered for solid detection in water,the
vibrating rod is to the density of water.In air or if covered by
water (density:1g/cm³/0.036 lbs/in)VEGAVIB 62 signals
uncovered.Only if the vibrating element is also covered with
solids (e.g.sand,sludge,gravel etc.) will the sensor signal
covered.
Fault monitoring
The electronics of VEGAVIB 62 continuously monitors the
following criteria:
lCorrect vibrating frequency
lLine break to the piezo drive
If one of the stated malfunctions is detected or in case of
power failure,the electronics takes on a defined switching
condition,i.e.the relay deenergises (safe condition).
The vibrating rod is piezoelectrically energised and vibrates at
its mechanical resonance frequency of approx.360 Hz.When
the vibrating rod is submerged in the product,the vibration
amplitude changes.This change is detected by the integrated
oscillator and converted into a switching command.
VEGAVIB 62 is a compact instrument,i.e.it can be operated
without external evaluation system.The integrated electronics
evaluates the level signal and outputs a switching signal.With
this switching signal,a connected device can be operated
directly (e.g.a warning system,aPLC,a pump etc.).
The data for power supply are stated in chapter "Technical
data"in the "Supplement".
