Product description
1.2 Application features
Applications
• Level measurement of liquids, limited use in
solids
• Measurement also in vacuum
• All slightly conductive materials and all
substances with a dielectric constant figure
ε
r
> 2,0 can be measured
• Measuring ranges 0 … 20 m
Two-wire technology
• Supply and output signal on one two-wire
line
• Output signal and signal processing
completely digital, hence maximum
accuracy
Rugged and abrasionproof
• Non-contact
• High resistance materials: PTFE, 1.4571
Exact and reliable
• Resolution 1 mm
• Unaffected by noise, vapours, dusts, gas
compositions and inert gas layering
• Unaffected by varying density and
temperature of the product
• Measurement of pressures up to 40 bar
and product temperatures up to 200°C
Communicative
• Individually connectable, with 15 sensors
on one two-wire line (digital output signal)
• Integral indication of measured values
• 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
1.3 Adjustment
Each measuring distance is different, hence
each radar sensor must be given some
basic information on the application and the
environment.
The adjustment and parameter adjustment of
the radar sensors is hence carried out with
- the PC and adjustment program VVO
- the detachable adjustment module
MINICOM
- the signal conditioning instrument
VEGAMET
Adjustment with PC
The set-up and adjustment of the radar
sensors is generally made on PC with
adjustment program VVO (
V EGA V isual O pe-
rating) under Windows ® .
The program leads quickly through the
adjustment and parameter adjustment via
pictures, graphics and process
visualisations.
The PC can be connected to any individual
position of the system or the signal line. It is
hence connected with the two-wire PC-
interface converter VEGACONNECT 2 to the
sensor, to the signal line or to the signal
conditioning instrument.
Adjustment with the PC on the digital signal
and supply line between the sensors and the
signal conditioning instrument VEGAMET
