3.2 Principle of operation

VEGAVIB 63 is a point level sensor with vibrating rod 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 overll and dry run protection. Thanks to its simple and robust measuring system, VEGAVIB 63 is virtually unaected 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 VEGAVIB 63 was ordered for solid detection in water, the vibrating rod is calibrated to the density of water. If covered by water (density: 1 g/cm³/0.036 lbs/in) VEGAVIB 63 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 module of VEGAVIB 63 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 dened current to the signal conditioning instrument. The connection cable to the vibrating element is also monitored.
Functional principle
Voltage supply
8 VEGAVIB 63 • - two-wire
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 electronics module and converted into a switching command.
Depending on your requirements, VEGAVIB 63 with two-wire electronics can be connected to dierent signal conditioning instru­ments. Compatible signal conditioning instruments are listed in chapter
"Technical data".
The data for power supply are specied in chapter "Technical data".
29280-EN-120418
3 Product description

3.3 Operation

With the factory setting, products with a density of > 0.05 g/cm³ (0.002 lbs/in³) can be measured. It is possible to adapt the instrument for products with lower density > 0.02 g/cm³ (0.0007 lbs/in³).
On the electronics module you will nd the following indicating and adjustment elements:
l Signal lamp for indication of the switching condition (green/red) l Potentiometer for adaptation to the product density l Mode changeover for selection of the output current

3.4 Storage and transport

Packaging
Transport
Transport inspection
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 tting, 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 nd the specications in chapter "Technical data" and on the type label.
In general, VEGAVIB 63 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.

10 VEGAVIB 63 • - two-wire
Do not hold VEGAVIB 63 on the vibrating element. Especially with
ange and tube versions, the sensor can be damaged by the weight of the instrument.
Remove the protective cover just before mounting.
The process tting 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 specied in chapter "Technical data" or on the type label of the sensor.
Handling
Agitators and uidiza-
tion
Inowing medium
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

Due to the eects of agitators, equipment vibration or similar, the level switch can be subjected to strong lateral forces. For this reason, do not use an overly long extension tube for VEGAVIB 63, but check if you can mount a short level switch on the side of the vessel in horizontal position.
Extreme vibration caused by the process or the equipment, e.g. agitators or turbulence in the vessel, e.g. by uidisation, can cause the extension tube of VEGAVIB 63 to vibrate in resonance. This leads to increased stress on the upper weld joint. Should a longer tube version be necessary, you can provide a suitable support directly above the vibrating element to secure the extension tube.
This measure applies mainly to applications in Ex areas. Make sure that the tube is not subject to bending stress due to this measure.
If VEGAVIB 63 is mounted in the lling st ream, unwanted false measurement signals can be generated. For this reason, mount VEGAVIB 63 at a position in the vessel where no disturbances, e.g. from lling openings, agitators, etc., can occur.
This applies particularly to instrument types with long extension tube.

Fig. 3: Inowing medium
Lock tting
Socket
Material cone
VEGAVIB 63 can be mounted with a lock tting for height adjustment. Take note of the pressure information of the lock tting.
The vibrating element should protrude into the vessel to avoid buildup. For that reason, avoid using mounting bosses for anges and screwed ttings. This applies particularly to use with adhesive products.
In silos for bulk solids, material cones can form and change the
switching point. Please keep this in mind when installing the sensor in the vessel. We recommend selecting an installation location where the vibrating rod detects an average value of the material cone.
The vibrating rod must be mounted in a way that takes the arrangement of the lling and emptying apertures into account.
To compensate measurement errors caused by the material cone in cylindrical vessels, the sensor must be mounted at a distance of d/6 from the vessel wall.
