Operation; Storage And Transport - Vega VEGASWING 51 Operating Instructions Manual

Functional principle

Packaging
VEGASWING 51 - - contactless electronic switch
allows use in vessels, tanks and pipes. Thanks to its simple
and robust measuring system, VEGASWING 51 is virtually
unaffected by the chemical and physical properties of the
liquid.
It functions even under difficult conditions such as turbulence,
air bubbles, foam generation, buildup, strong external vibration
or changing products.
Fault monitoring
The electronics module of VEGASWING 51 continuously
monitors via frequency evaluation the following criteria:
Strong corrosion or damage on the tuning fork
l
loss of vibration
l
Line break to the piezo drive
l
If a malfunction is detected or in case of power failure, the
electronics takes on a defined switching condition, i.e. the
contactless electronic switch opens (safe condition).
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 1200 Hz. The
piezos are fixed mechanically and are hence not subject to
temperature shock limitations. The frequency changes when
the tuning fork is covered by the medium. This change is
detected by the integrated oscillator and converted into a
switching command.
VEGASWING 51 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, a PLC, a pump etc.).
The data for power supply are stated in chapter "Technical
data" in the "Supplement".

3.3 Operation

The switching status of VEGASWING 51 can be checked with
closed housing (signal lamp). Products with a density >0.7 g/
cm³ (>0.025 lbs/in³) can be detected.

3.4 Storage and transport

Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test according to DIN EN 24180.
