User Manual

The antenna of the radar sensor emits short radar
pulses with a duration of approx. 1 ns. These pulses are
reflected by the product and received by the antenna as
echoes. The running time of the radar pulses from
emission to reception is proportional to the distance and
hence to the level. The determined level is converted
into an appropriate output signal and outputted as
measured value.
Two-wire electronics 4 ... 20 mA/HART for power supply
and measured value transmission on the same cable.
The power supply range can differ depending on the
instrument version. The exact range is stated in the
Technical data in the Supplement.
3.3 Adjustment
VEGAPULS 68 can be adjusted with three different
adjustment media:
l the indicating and adjustment module PLICSCOM
l an adjustment software acc. to FDT/DTM standard,
e.g. PACTware™ and PC
l a HART handheld
The entered parameters are generally saved in VEGA-
PULS 68, optionally also in PLICSCOM or in
PACTware™.
3.4 Storage and transport
Your instrument was protected by packaging during
transport. Its capacity to handle normal loads during
transport is assured by a test acc. to EN 24180.
The packaging of standard instruments consists of
environment-friendly, recyclable cardboard. For special
versions PE foam or PE foil can be also used. Dispose
of the packaging material via specialised recycling
companies.
