VEGABAR 87 • Modbus and Levelmaster protocol
46297-EN-220624
Temperature sensors in the ceramic diaphragm and the ceramic base
of the CERTEC
®
measuring cell detect the actual process tempera-
ture. The temperature value is output via:
•
The display and adjustment module
•
The current output or the additional current output
•
The digital signal output
The measuring cell design depends on the selected pressure type.
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.
Relative pressure, climate-compensated
: the measuring cell is
evacuated and encapsulated. The ambient pressure is detected
through a reference sensor in the electronics and compensated. It
thus has no influence on the measured value.
The measuring system is completely welded and hence sealed
against the process. The sealing of the process fitting against the
process is carried out by a seal provided on site.
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.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
•
Not in the open
•
Dry and dust free
•
Not exposed to corrosive media
•
Protected against solar radiation
•
Avoiding mechanical shock and vibration
