1.2 Application features
Applications
• level measurement of liquids and solids
• measurement also in vacuum
• all slightly conductive materials and sub-
stances with a dielectric constant
ε
r
> 2,0 can be measured
• measuring ranges 0 … 20 m
Two-wire technology
• supply and output signal on one two-wire
line
• 4 … 20 mA-output signal or digital output
signal
Rugged and abrasion proof
• non-contact
• high resistance materials
Exact and reliable
• resolution 1 mm
• unaffected by noise, vapours, dusts, gas
compositions and inert gas layering
• unaffected by varying density and tempera-
ture of the medium
• measurement with pressures up to 64 bar
and medium temperatures up to 350
°
C
Communicative
• individually connectable, with 15 sensors on
one two-wire line (digital output signal)
• integral measured value indication
• optionally indication separated from the
sensor
• connection to all BUS-systems: Interbus␣ S,
Modbus, Siemens 3964R, Profibus DP,
Profibus FMS, ASCII
• adjustment from the DCS-stage
Ex-approvals
• CENELEC, FM, CSA, ABS, LRS, GL, LR,
ATEX, PTB
Product description
ductivity or with the dielectric constant of the
medium. Hence virtually all mediums can be
measured.
Due to standard flanges from DN 50 to
DN 250, ANSI 2“ to ANSI 10“ the sensor an-
tenna systems are adapted to the various
measured products and process environ-
ments. High-quality materials withstand also
extremely chemical and physical conditions.
The sensors deliver reliably, precise and
longterm stable, reproducible analogue or
digital level signals.
Continuous and reliably
Unaffected by temperature, pressure and
atmosphere type, VEGAPULS radar sensors
detect quickly and precise levels of different
mediums.
