VEGA VEGAPULS 81 - Manual (Page 5)

VEGAPULS 64 and 81 5
1.2 Application features
• Level, difference and object measurement
on liquids and solids.
• Measuring range 0 … 35 m.
• Non-contact and abrasion free.
• Measurement under operating pressures up
to 64 bar and product temperatures of more
than 1000 ° C.
• Approved in all Ex-zones (PTB, CENELEC,
FM, CSA).
• Ship and offshore approvals (GL, LRS,
ABS).
• Digital or analogue 0 … 20 mA measuring
signal.
• Individual outputs: e.g. current, voltage,
relay, transistor…
• Connection to all BUS-systems such as
Siemens 3964 R, Interbus S, Profibus,
Modbus…
• Up to 15 sensors to a two-wire line.
• Measurement through vessel walls of plastic
vessels.
• Sea-water resistant, chemically high-resist-
ance: PTFE, 1.4571 (stst), alloy C2 (2.4602),
alloy C4 (2.4610), Tantalum, GK-AlSi11
powder-coated(3.2211.02).
• Unaffected by temperature changes and
product density.
• Unaffected by noise, steam, dust, gas com-
positions or innert gas layering.
• All slightly conductive products and prod-
ucts with a dielectric constant ε
r
> 1,5 can
be measured.
• Indication of measured values integrated in
the sensor (VEGAPULS 81); optionally exter-
nal indication of measured values, which
can be mounted at a distance of up to 25 m
away from the sensor in Ex-zone 0.
• No approval necessary: General telecom-
munication approval (approved for opera-
tion outside and outside closed metallic
vessels).
Product description
1.3 Adjustment
Each application is unique, hence each radar
sensor requires some basic information on
application and environment.
Operation and parameter adjustment on the
radar sensors is carried out with
- PC or
- signal conditioning instrument.
Adjustment with PC
The set-up and adjustment of VEGAPULS
radar sensors is generally made on the PC
with the adjustment program VVO (VEGA
Visual Operating) under Windows ® . The pro-
gram is menu-guided by pictures, graphics
and process visualizations for quick operation
and parameter adjustment.
Sensor with analogue 0 … 20 mA-signal output
(compact instrument), adjustment with PC on
the sensor signal line or directly on the sensor
