1.2 Application features
Applications
• level measurement of any liquid
• measurement also in vacuum
• all slightly conductive materials and all
substances with a dielectric constant > 2.0
can be measured
• measuring range 0 … 10 m.
Two-wire technology
• power supply and output signal on one
two-wire cable (loop powered)
• Profibus PA (Profile 3).
Rugged and abrasionproof
• non-contact
• high-resistance materials
Exact and reliable
• accuracy 0.05 %.
• resolution 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 3 bar and
product temperatures up to 150°C.
Communicative
• integrated measured value display
• optional display module separate from
sensor
• adjustment with detachable adjustment
module, pluggable in the sensor or in the
external display
• adjustment with HART ® handheld
• adjustment with the PC.
Approvals
• CENELEC, ATEX, PTB, FM, CSA, ABS,
LRS, GL, LR, FCC.
With standard flanges of DN 50 to DN 150,
ANSI 2“ to ANSI 6“ or G 1½ A and 1½“ NPT,
the sensor antenna systems can be adapted
to various products and measuring environ-
ments.
The high-quality materials can also withstand
extreme chemical and physical conditions.
The sensors deliver stable, reproducible
analogue or digital level signals with reliability
and precision.
Continuous and reliable
Unaffected by temperature, pressure and
individual atmosphere content, VEGAPULS
radar sensors are used for quick and reliable
continuous level measurement of widely vary-
ing products.
