3 Product description
3.2 Principle of operation
Application area
Functional principle
VEGAWAVE 61 is a point 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 61 is virtually
unaffected by the chemical and physical properties of the bulk solid.
It also works when subjected to strong external vibrations or changing
products.
Solid detection in water
If VEGAWAVE 61 was ordered for solids detection in water, the tuning
fork is set to the density of water. In air or when immersed in water
(density: 1 g/cm³/0.036 lbs/in), VEGAWAVE 61 signals "uncovered".
Only when the vibrating element is also covered with solids (e.g. sand,
sludge, gravel etc.) will the sensor signal "covered".
Fault monitoring
The electronics module of VEGAWAVE 61 monitors continuously the
following criteria:
l Correct vibrating frequency
l Line break to the piezo drive
If one of these faults is detected, the electronics signals this via a
defined current to the signal conditioning instrument. The connection
cable to the vibrating element is also monitored.
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 150 Hz. When the tuning
fork is submerged in the product, the vibration amplitude changes.
This change is detected by the integrated electronics module and
converted into a switching command.
Voltage supply
Depending on your requirements, VEGAWAVE 61 with two-wire
electronics can be connected to different signal conditioning instruments. Compatible signal conditioning instruments are listed in chapter
"Technical data".
The data for power supply are specified in chapter "Technical data".
3.3 Operation
With the factory setting, products with a density of > 0.02 g/cm³
(0.0008 lbs/in³) can be measured. The instrument can also be adapted
to products with lower density > 0.008 g/cm³ (0.0003 lbs/in³).
On the electronics module you will find the following indicating and
adjustment elements:
l Signal lamp for indication of the switching condition (green/red)

Storage
Storage and transport
temperature
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.
The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. In addition, the sensor is provided with
a protective cover of cardboard. For special versions PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration
l Storage and transport temperature see chapter "Supplement -
Technical data - Ambient conditions"
l Relative humidity 20 … 85 %

4.1 General instructions
Suitability for the process conditions
Switching point
Moisture
Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
In general, VEGAWAVE 61 can be installed in any position. The
instrument only has to be mounted in such a way that the vibrating
element is at the height of the desired switching point.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

Do not hold VEGAWAVE 61 on the vibrating element. Especially with
flange and tube versions, the sensor can be damaged by the weight of
the instrument.
Remove the protective cover just before mounting.
The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.

The max. permissible pressure is specified in chapter "Technical data"

Handling
Socket
Filling opening
The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for scr ewing in.
4.2 Instructions for installation
The vibrating element should protrude into the vessel to avoid buildup.
For that reason, avoid using mounting bosses for flanges and screwed
fittings. This applies particularly to use with adhesive products.
Mount the instrument in such a way that the tuning fork does not
protrude directly into the filling stream.

b Concave protective sheet for abrasive solids
If such an installation location should be necessary, mount a suitable
protective sheet above or in front of the vibrating element, see
illustration "a").
In abrasive solids, mounting according to illustration "b" has proven. A
spout forms in the concave protective sheet preventing wear of the
protective sheet.

4 Mounting
Horizontal installation
Inflowing medium
To achieve a very precise switching point, you can install VEGAWAVE
61 horizontally. However, if the switching point can have a tolerance of
a few centimeters, we recommend mounting VEGAWAVE 61 approx.
20° inclined to the vessel bottom to avoid buildup.
Fig. 4: Horizontal installation
If VEGAWAVE 61 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
VEGAWAVE 61 at a position in the vessel where no disturbances, e.g.
from filling openings, agitators, etc., can occur.
Flows
To minimise flow resistance caused by the tuning fork, VEGAWAVE
61 should be mounted in such a way that the surfaces of the blades
are parallel to the product movement.
