2.7 Fulfilling of NAMUR recommendations
With respect to interference resistance and emitted interference, the NAMUR recommendation NE 21 is fulfilled.
With respect to compatibility, the NAMUR recommendation NE 53 is fulfilled. This applies also to the corresponding indicating and adjustment components. VEGA instruments are generally upward and downward compatible.
•Sensor software for DTM VEGAWELL 72 HART
•DTM VEGAWELL 72 for adjustment software PACTware
The parameter adjustment of the basic sensor functions is independent of the software version. The range of available functions depends on the respective software version of the individual components.
The software version of the instrument can be read out via
PACTware.

|
3.2 Principle of operation |
Application range |
VEGAWELL 72 is used for level and gauge measurement in |
|
wells, basins and atmospherically open vessels particularly in |
|
the water/waste water industry as well as in the shipbuilding |
|
industry.1) |
Functional principle |
The actual sensor element is the CERTEC® measuring cell |
|
with rugged ceramic diaphragm. The hydrostatic pressure |
|
causes a capacitance change in the measuring cell via the |
|
ceramic diaphragm. This change is converted into an |
|
appropriate output signal. |
Voltage supply |
Two-wire electronics 4 … 20 mA/HART for power supply and |
|
measured value transmission over the same cable. |
|
The supply voltage range can di er depending on the |
|
instrument version. |
|
Data for power supply are specified in chapter "Technical |
|
data". |
VEGAWELL 72 - 4 … 20 mA/HART can be adjusted with di erent adjustment media:
• with external adjustment/indication VEGADIS 12
• an adjustment software according to FDT/DTM standard,
|
|
e.g. PACTware and PC |
|
• With a HART handheld |
|
|
The type of adjustment and the adjustment options depend on |
|
|
the selected adjustment component. The entered parameters |
|
|
are generally saved in the respective sensor, when adjusting |
|
|
with PACTware™ and PC optionally also in the PC. |
|
|
3.4 Packaging, transport and storage |
|
Packaging |
Your instrument was protected by packaging during transport. |
|
|
Its capacity to handle normal loads during transport is assured |
|
|
by a test according to DIN EN 24180. |
|
|
The packaging of standard instruments consists of environ- |
|
|
ment-friendly, recyclable cardboard. For special versions, PE |
|
|
foam or PE foil is also used. Dispose of the packaging material |
|
|
via specialised recycling companies. |
|
|
1) |
For use in closed vessels under vacuum, VEGAWELL 72 is available with |
|
|
|
|
|
absolute pressure measuring ranges. |

3 Product description |
Transport |
Transport must be carried out under consideration of the notes |
|
on the transport packaging. Nonobservance of these instruc- |
|
tions can cause damage to the device. |
Transport inspection The delivery must be checked for completeness and possible transit damage immediately at receipt. Ascertained transit damage or concealed defects must be appropriately dealt with.
Storage
Storage and transport temperature

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
•Storage and transport temperature see "Supplement -

General instructions |
Mounting position |
Note the following points when selecting the installation |
|
|
location. |
•Sideways movements of the transmitter can cause measurement errors
àTherefore, mount VEGAWELL 72 in a calm area or in a suitable protective tube
Information:
We recommend the measuring instrument holder from the VEGA line of accessories (article no. BARMONT.B) for fastening VEGAWELL 72.
•The protective cover prevents mechanical damage to the measuring cell. It should only be removed when the sensor is deployed in extremely polluted water.
Pressure compensation Note the following item for pressure compensation:
•The connection cable has a capillary for atmospheric pressure compensation
àTherefore lead the cable end into a dry space or directly into a suitable connection housing.
Information:
VEGA recommends VEGABOX 02 or VEGADIS 12 as connection housing. Both contain the terminals as well as a filter element for pressure compensation. For mounting outdoors, a suitable protective cover is available. On VEGAWELL 72 with plastic housing, the terminals and the filter element are already integrated in the plastic housing.
