VEGABAR 86 • Secondary Device for electronic differential pressure
48048-EN-220817
Extreme process temperature jumps are also immediately detected
by the ø 28 mm measuring cell. The values are compared with that of
an additional temperature measurement on the ceramic base body.
Within only a few measuring cycles the intelligent sensor electronics
compensates unavoidable measurement deviations due to tempera-
ture shocks. Such shocks cause (depending on the set damping) only
slight, brief changes to the output signal.
Relative pressure
: the measuring cell is open to the atmosphere.
The ambient pressure is detected in the measuring cell and compen-
sated. It thus has no influence on the measured value.
Absolute pressure
: the measuring cell contains vacuum and is
encapsulated. The ambient pressure is not compensated and does
hence influence the measured value.
The following illustration shows the installation of the ceramic measur-
ing cell in the sensor as well as the sealing concept.

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 consists of environment-friendly, recyclable card-
board. 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.
