3.2 Principle of operation
The LEVEL TRANSMITTER 8138 is a radar sensor for continuous
level measurement of aggressive liquids or with hygienic require-
ments. It is suitable for applications in storage tanks, process vessels,
dosing vessels and reactors.
The standard electronics enables the use of instruments in products
with an ε -Wert ≥1.8. The electronics version with increased sensitivity
r
enables the use of the instrument also in applications with very poor
reflective properties or products with an ε
can be actually reached depend on the measurement conditions, the
antenna system or the standpipe or bypass tube.
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.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
