3.2 Principle of operation
The VEGAPULS SR 68 is a radar sensor for continuous measurement
of bulk solids also under difficult process conditions. It is particularly
suitable for level measurement in high silos and large bunkers.
The instrument is also suitable for applications in liquids.
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 transit 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 appropri-
ate output signal and outputted as measured value.
3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
