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".

3.3 Operation

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.

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.

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.
