1.1 Function and configuration
VEGASWING series 80 A vibrating level
switches detect the levels of liquids with a
viscosity between 0,2 mPa s and
10.000 mPa s and densities ³ 0,5 g/cm3.
Their modular design allows them to be used
in vessels, tanks and pipelines. T ypical applications involve overfill and dry run protection.
Thanks to its simple and rugged measuring
system, VEGASWING can be used in almost
any liquid regardless of its chemical and
physical properties. It also works well under
difficultconditions such as turbulence, air
pockets, foam formation, or changes in material, and is insensitive to external vibrations.
VEGASWING with their mechanical connection thread, cone, bolting and flange are also
suitable for level detection of liquids in the
food processing industr y. The tuning fork
and the extension tube are polished for such
applications.
For the use in very aggressive products,
Hastelloy C4 and coatings ECTFE (Halar)
and enamel are used for VEGASWING 81 A
and 83 A.
For product temperatures of more than
100°C up to 150°C, VEGASWING 81 A and
83 A can be equipped with a temperature
adapter.
Function
The tuning fork is piezoelectrically energised
and vibrates at a resonance frequency of
approx. 400 Hz. The resonance frequency
changes when the tuning fork is covered by
the material. This frequency change is detected by the integral oscillator and converted into a switching command.The
switching condition (overfill or dry run protection) can be selected using the mode switch.
The oscillator of VEGASWING continuously
monitors the instrument for the following
faults:
- tuning fork corrosion or damage,
- absence of vibration,
- piezo drive cable malfunction,
- vibrating frequency too low ,
- corrosive medium penetrating the sensor
from the vessel.
With a connected signal conditioning instrument (oscillator SWING E82 Z) in addition
more functions can be monitored. With oscillator SWING E82 Z and appropriate signal
conditioning instrument, the function of the
complete measuring chain can be monitored
at the touch of a button. This is valid according to the general type approval acc. to WHG
as recurring test. More information is provided with the particular signal conditioning
instrument.
Should one of the above-mentioned faults
occur, or the power supply fails, the electr onics react by switching to a defined switching
state, i.e. dependent on the electr onics version
- opening the non-contact switch,
- de-energising the r elay, or
- blocking the output transistor .
With the two-wire output version, the failure is
signalled via a defined current to the connected VEGATOR signal conditioning instrument.

Product description
Recurring test acc. to WHG
According to the type approval WHG
(Z-65.11-154) the recurring test acc. to WHG
can be carried out by pressing a key on the
VEGATOR 536 EX, 537 EX, 636 EX signal
conditioning instrument. The sensor must not
be removed, nor made to respond by filling
the vessel. This is valid for VEGASWING
81 A EX and 83 A EX with two-wire
SWING E82 Z EX oscillator .
VEGASWING 81 A EX and 83 A EX meet the
fail-safe requirements to class 3 (AK 1 … 3)
acc. of DIN 19 251 in mode A (overfill protection).
Configuration
A measuring system consists of:
- a VEGASWING with SWING E82 C,
SWING E82 R or SWING E82 T oscillator
- external instruments, switched by VEGASWING
or
- a VEGASWING with SWING E82 Z or
SWING E82 Z EX oscillator
- VEGATOR 536 EX, 537 EX or 636 EX signal
conditioning instrument or an already
mounted instrument, e.g. VEGA TOR
425 EX, 534 EX, 825 EX
- external instruments switched by VEGATOR.
1.2 Approvals
Explosion protection
Only certified VEGASWING 81A EX0, 83A
EX0 vibrating level switches should be used
in hazardous areas caused by combustible
gases, vapours or fog, . VEGASWING
81A EX0, 83A EX0 are suitable for use in
hazardous areas zone 1 and zone 0.
The EU-type approval issued by the approval authority is attached to the instruments
as proof of explosion protection. Ex-mounting
regulations should be noted when VEGASWING 81A EX0, 83A EX0 vibrating level
switches are mounted and operated in hazardous areas. The information and conditions
of the supplied certificates (EU-type approval, conformity certificate) for VEGASWING 81A EX0, 83A EX0 as well as the
appropriate electrical equipment (VEGA TOR
signal conditioning instrument, separator ,
safety barrier) must be taken into account.
• The mounting of Ex-systems must always
be carried out by skilled staff.
• VEGASWING 81A EX0, 83A EX0 must be
powered by an intrinsically safe circuit; the
permissible electrical values are stated in
the appropriate Ex-type approval certificate.
• VEGASWING 81A EX0, 83A EX0 with
enamelled tuning fork or plastic parts acquiring static electricity have a warning
label stating the measures to be taken to
avoid dangers due to electrostatic discharges. The contents of the warning label
should be noted.
• The explosion protection of the electrical
equipment used is only ensured when the
limit temperatures stated in the certificate
are not exceeded.
• In the case of dangers due to oscillation
and vibrations, the appropriate parts of
VEGASWING 83A EX0 should be secured
effectively against these dangers.

Overfill protection
The information and conditions of the supplied general type approvals must be noted
when a VEGASWING is used as part of an
overfill protection for vessels storing water endangered liquids. The general type approval should be available at the place of
installation place.
VEGASWING should only be used in liquids
against which the materials of the wetted
parts of VEGASWING are sufficiently chemically resistant.
