VEGASWING 51 • - transistor (PNP)
It is designed for industrial use in all areas of process technology and
can be used in liquids.
Typical applications are overfill and dry run protection. With a tuning
fork of only 38 mm length, VEGASWING 51 can be also mounted e.g.
in pipelines from DN 25. The small tuning fork 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 bub-
bles, foam generation, buildup, strong external vibration or changing
products.
Function monitoring
The electronics module of VEGASWING 51 continuously monitors via
frequency evaluation the following criteria:
•
Strong corrosion or damage on the tuning fork
•
Loss of vibration
•
Line break to the piezo drive
If a malfunction is detected or in case of power failure, the electronics
takes on a defined switching condition, i.e. the output is open (safe
condition).
The tuning fork is piezoelectrically energised and vibrates at its me-
chanical resonance frequency of approx. 1100 Hz. When the tuning
fork is submerged in the product, the frequency changes. This change
is detected by the integrated electronics module and converted into a
switching command.
VEGASWING 51 is a compact instrument, i.e. it can be operated with-
out 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 pump etc.).
The data for power supply are specified in chapter "Technical data".
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.

Storage and transport

Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
