2.6Safety information for Ex areas
Please note the Ex-specific safety information for installation
and operation in Ex areas.These safety instructions are part of
the operating instructions manual and come with the Ex-
approved instruments.
2.7Environmental instructions
Protection of the environment is one of our most important
duties.That is why we have introduced an environment
management system with the goal of continuously improving
company environmental protection.The environment man-
agement system is certified acc.to DIN EN ISO 14001.
Please help us fulfil this obligation by observing the environ-
mental instructions in this manual:

3.2Principle of operation
VEGACAP 66 is a level sensor with fully insulated capacitive
electrode for level detection.
VEGACAP 66 is very rugged and maintenance-free and can
be used in all areas of industrial process technology.
Fully insulated probes such as VEGACAP 66 are used in
solids as well as in liquids.
Typical applications are overfill and dry run protection.
The capacitive measuring principle places no special require-
ments on installation.Hence,many different applications can
be equipped with VEGACAP 66.
Problem-free use in adhesive or corrosive products.
The probe,the measured product and the vessel wall form an
electrical capacitor.The capacitance is influenced by three
main factors:
1
2
3
Fig.2:Functional principle -Plate capacitor
1Distance between the electrode surfaces
2Size of the electrode surfaces
3Type of dielectric between the electrodes
The probe and the vessel wall are the capacitor plates.The
measured product is the dielectric.Due to the higher dielectric
constant (DK value)of the product compared to air,the
capacitance increases as the material gradually covers the
probe.
The capacitance change is converted by the oscillator into a
switching command.

Product description
30020-EN-050920

VEGACAP 66 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,aPLC,a pump etc.).
The exact range of the power supply is stated in the Technical
data in the Supplement.
3.3Adjustment
The probe can be adapted to the dielectric constant of the
product directly on the electronics module.
Aswitching command can be triggered when the probe is
covered or laid bare.
On the electronics module you will find the following indicating
and adjustment elements:
lsignal lamp for indication of the switching condition (green/
red)
lPotentiometer for switching point adaptation
lDIL switch for measuring range selection
lDIL switch for mode adjustment
3.4Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc.to DIN 55439.
The packaging of standard instruments consists of environ-
ment-friendly,recyclable cardboard.For special versions,PE
foam or PE foil is also used.Dispose of the packaging material
via specialised recycling companies.
lStorage and transport temperature see "Supplement -
Technical data -Ambient conditions"
lRelative humidity 20 ... 85 %

4Mounting
4.1General instructions
In general,VEGACAP 66 can be mounted in any position.The
instrument must be mounted in such a way that the probe is at
the height of the requested switching point.
With screwed versions,the housing must not be used for
screwing in!Tightening can cause damages on the locking
piston of the housing.
To screw in,use the hexagon above the thread.
Use the recommended cable (see chapter "Connecting to
power supply")and tighten the cable gland.
You can give your VEGACAP 66 additional protection against
moisture penetration by leading the connection cable down-
ward in front of the cable entry.Rain and condensation water
can thus drain off.This applies mainly to mounting outdoors,in
areas where moisture is expected (e.g.by cleaning processes)
or on cooled or heated vessels.
Fig.3:Measures against moisture penetration
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.
