3.2 Principle of operation

VEGASON 62 is an ultrasonic sensor for continuous level measure-

ment. It is suitable for liquids and solids in virtually all industries,

particularly in the water and waste water industry.

The transducer of the ultrasonic sensor transmits short ultrasonic

pulsestothemeasuredproduct.Thesepulsesarereectedby

product surface and received back by the transducer as echoes.

The running time of the ultrasonic pulses from emission to reception

is proportional to the distance and hence the level. The determined

level is converted into an appropriate output signal and outputted as

measured value.

ured value transmission on the same cable.

Thesupplyvoltagerangecandierdependingontheinstrument

version.

Thedataforpowersupplyarespeciedinchapter"Technical data".

The backlight of the display and adjustment module is powered by

the sensor. The prerequisite for this is a supply voltage at a certain

level.Theexactvoltagespecicationsarestatedinchapter"Technical

data".

Theoptionalheatingrequiresitsownvoltagesupply.Youcannd

further details in the supplementary instructions manual "Heating for

display and adjustment module".

This function is generally not available for approved instruments.

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.

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 chapter "Supplement -

Technical data - Ambient conditions"

•

Relative humidity 20 … 85 %

With instrument weights of more than 18 kg (39.68 lbs) suitable and

approved equipment must be used for lifting and carrying.

properties of the medium.

Youcanndthespecicationsinchapter"Technical data" and on the

The instrument is suitable for standard and extended ambient condi-

tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.

module. The housing can be rotated by 330° without the use of any

tools. You can also install the display and adjustment module in four

dierentpositions(eachdisplacedby90°).

Use the recommended cables (see chapter "Connecting to power

supply") and tighten the cable gland.

You can give your instrument additional protection against moisture

penetration by leading the connection cable downward in front of the

cablegland.Rainandcondensationwatercanthusdraino.This

applies mainly to outdoor mounting as well as installation in areas

where high humidity is expected (e.g. through cleaning processes) or

on cooled or heated vessels.

To maintain the housing protection, make sure that the housing lid is

closed during operation and locked, if necessary.

Fig. 2: Measures against moisture ingress

Metric threads

In the case of instrument housings with metric thread, the cable

glands are screwed in at the factory. They are sealed with plastic

plugs as transport protection.

You have to remove these plugs before electrical connection.

NPTthread

In the case of instrument housings with self-sealing NPT threads, it is

not possible to have the cable entries screwed in at the factory. The

free openings for the cable glands are therefore covered with red dust

protection caps as transport protection.

Prior to setup you have to replace these protective caps with ap-

proved cable glands or close the openings with suitable blind plugs.

The reference plane for the measuring range is the lower edge of the

chapter "Technical data".

Warning:

The housing must not be used to screw the instrument in! Applying

tightening force can damage internal parts of the housing.

When mounting the sensor, keep a distance of at least 200 mm

(7.874 in) to the vessel wall. If the sensor is installed in the center of

dished or round vessel tops, multiple echoes can arise. These can,

however, be suppressed by an appropriate adjustment (see chapter

"Setup").

> 200 mm

Fig. 5: Mounting on round vessel tops

2 Vessel center or symmetry axis

If this distance cannot be maintained, a false signal suppression

should be carried out during setup. This applies particularly if buildup

on the vessel wall is expected. In such cases, we recommend repeat-

ing the false signal suppression at a later date with existing buildup.

In vessels with conical bottom it can be advantageous to mount the

sensor in the centre of the vessel, as measurement is then possible

down to the bottom.
