3.2Principle of operation
VEGACAP 67 is a point level sensor with capacitive probe for level
detection under high process temperatures.
VEGACAP 67 is very rugged and maintenance-free and can be used
in all areas of industrial process technology.
Probes such as VEGACAP 67 are used in solids applications.
The range of the process temperature is at -50 …+300 °C
(-58 …+572 °F). With external housing of -50 …+400 °C
(-58 …+752 °F).
Typical applications are overfill and dry run protection.
The capacitive measuring principle places no special requirements on
installation.Hence,many different applications can be equipped with
VEGACAP 67.
Probe,measured product and vessel wall form an electrical capacitor.
The capacitance is influenced by three main factors.

3Product description
31314-EN-100407

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 probe is gradually covered.
The capacitance change is converted by the electronics module into a
switching command.
VEGACAP 67 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,a
PLC,a pump etc.).
The data for power supply are specified in chapter "Technical data".
3.3Operation
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
according to DIN EN 24180.
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.
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.
