1.2 Application features
Applications
• level measurement of liquids and solids
• measurement also in vacuum
• all slightly conductive materials and all
substances with a dielectric constant > 2.0
can be measured
• measuring range 0 … 20 m
Two-wire technology
• power supply and output signal on one
two-wire cable

Exact and reliable
• accuracy 1 mm
• unaffected by noise, vapours, dusts, gas
compositions and inert gas stratification
• unaffected by varying density and tem-
perature of the medium
• measurement in pressures up to 64 bar
and product temperatures up to 350°C
Communicative
• individual connection, with 15 sensors on
one two-wire cable (digital output signal)
• integrated measured value display
• optional display module separate from
sensor
• connection to all BUS systems: Interbus S,
Modbus, Siemens 3964R, Profibus DP,
Profibus FMS, ASCII
• adjustment from the PLC level
Ex approvals
• CENELEC, FM, CSA, ABS, LRS, GL, LR,
ATEX, PTB
Product description
Signal reflectivity grows stronger with in-
creasing conductivity or increasing dielectric
constant of the product. Hence, nearly all
substances can be measured.
With standard flanges from DN 50 up to DN
250, ANSI 2“ up to ANSI 10“ the sensor an-
tenna systems are adapted to the various
products and process environments. The
high-quality materials withstand extreme
chemical and physical conditions. The sen-
sors deliver stable, reproducible analogue or
digital level signals with reliability and preci-
sion, and have a long useful life.
Continuous and accurate
Unaffected by temperature, pressure and
atmosphere content, VEGAPULS radar sen-
sors measure quickly and accurately the
levels of widely varying products.
Temperature influence: Temperature error absolutely
zero (e.g. at 500°C 0.018 %)
Pressure influence: Error with pressure increase very
low (e.g. at 50 bar 0.8 %)

VEGAPULS 56 sensors now make radar level
measurement possible in plants where it was
hitherto unthinkable.
