1.1 Configuration
Scope of delivery
The scope of delivery encompasses:
• the VEGAFLEX 62 level sensor
• documentation
- operating instructions manual
- Ex-specific safety instructions (with Ex
versions) and, if necessary, further certifi-
cates.
Components
VEGAFLEX consists of the following com-
ponents:
• process connection with electrode
• housing with electronics
• housing cover with indicating and adjustment
module PLICSCOM (option)
1.2 Principle of operation
Area of application
VEGAFLEX 62 is a level senor with cable or rod
electrode for continuous level measurement.
It is designed for industrial use in all areas of
process technology and is suitable for the
measurement of liquids and solids.
Physical principle
High frequency microwave impulses are
guided along a steel cable or rod. The micro-
wave impulses are reflected when they reach
the product surface. The impulse running time
is processed by the integrated electronics and
outputted as distance.
Power supply
VEGAFLEX has a two-wire electronics
4 … 20 mA/HART®for power supply with
14 … 36 V DC.
1.3 Adjustment
VEGAFLEX can be adjusted with three different
media:
• the indicating and adjustment module
PLICSCOM
• the adjustment software acc. to FDT/DTM
standard, e.g. PACT
ware
TM and PC
• a HART®handheld.

2.1 Preparing the connection
Take note of safety instructions for Ex
applications
In hazardous areas you should take
note of the appropriate regulations and
type approval certificates of the sen-
sors and power supply units. The sen-
sors must only be operated on intrinsically safe
circuits. The permissible electrical values are
stated in the certificate.
Select voltage supply
VEGAFLEX requires a supply voltage of
14 … 36 V DC. Power supply and current signal
are led via the same two-wire connection cable.
Provide a reliable separation between the exter-
nal energy source and the mains circuits acc. to
DIN VDE 0106 part 101. The VEGA power supply
units VEGATRENN 149AEx, VEGASTAB 690,
VEGADIS 371 as well as all VEGAMETs meet this
requirement. When using one of these instru-
ments, protection class II is ensured for
VEGAFLEX 62.
Bear in mind the following factors regarding
supply voltage:
• Reduction of the output voltage of the power
supply unit under nominal load
• Influence of additional instruments in the cir-
cuit (see load values in Technical data).
Anschlusskabel auswählenSelect connec-
tion cable
VEGAFLEX is connected with standard two-wire
cable. An outer diameter of 5 … 9 mm ensures
the seal effect of the cable entry.
If strong electromagnetic interference is ex-
pected, shielded cable is recommended. The
screen should be applied on both ends.
Select connection cable for Ex
applications
Take note of the corresponding installa-
tion regulations for Ex applications.
