3.2 Principle of operation
The instrument is suitable for bulk solid applications on conveyor belts
and screw conveyors.There are application possibilities in nearly all
areas of industry.
In radiation-based measurement, a Caesium-137 or Cobalt-60 iso-
tope emits focussed gamma rays that are attenuated when penetrat-
ingtheconveyorbeltandthemedium.ThePVTdetectoronthelower
side of the conveyor belt receives the radiation, whose strength is
proportional to the density.The measuring principle has proven to be
very reliable in conjunction with extreme process conditions because
it measures contactlessly from outside through the conveyor belt.The
measuring system ensures maximum safety, reliability and plant avail-
ability, independently of the medium and its properties.
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 %

3.4 Accessories and replacement parts
The display module PLICSCOM is used for measured value indication
and diagnosis. It can be inserted into the sensor and removed at any
time.
TheinterfaceadapterVEGACONNECTenablestheconnectionof
communication-capable instruments to the USB interface of a PC. For
parameter adjustment of these instruments, the adjustment software
PACTwarewithVEGA-DTMisrequired.
Youcanndfurtherinformationintheoperatinginstructions"Interface
adapter VEGACONNECT" (Document-ID 32628).
VEGADIS61isanexternaldisplayunitforsensorswithsinglecham-
ber housing and Ex-d double chamber housing.
It is suitable for measured value indication and is connected to the
sensor with a four-wire standard cable up to 50 m long.
Youcanndfurtherinformationintheoperatinginstructions"VE-
GADIS 61" (Document-ID 27720).
TheVEGADIS62issuitableformeasuredvalueindicationofsensors.
It is looped into the 4 … 20 mA/HART signal cable.
Youcanndfurtherinformationintheoperatinginstructions"VE-
GADIS 62" (Document-ID 36469).
TheelectronicsmodulePT30E.XXisareplacementpartforradiation-
based sensors WEIGHTRAC 31.
TheelectronicsmodulecanonlybeexchangedbyVEGAservice
technician.
If you have ordered WEIGHTRAC 31 without a measuring frame, a
basic mounting set is enclosed with the instrument. It includes every-
thing needed to fasten the measuring tube reliably.
The corresponding measuring frame and mounting accessories can
be ordered optionally.
Use a tachometer for detection of the belt speed.The tachometer can
be connected to the input of the WEIGHTRAC 31.
3.5 Corresponding source container
An isotope in a suitable source container (e.g. SHLD-1) is the prereq-
uisite for a radiation-based measurement setup.
The handling of radioactive substances is regulated by law. The radia-
tion protection rules of the country in which the system is operated
applyrstandforemost.
In Germany, for example, the current radiation protection ordinance
(StrlSchV)basedontheAtomicEnergyLaw(AtG)applies.
The following points are important for measurement with radiation-
based methods:
Indicating module
VEGACONNECT
External display and
adjustment unit
External indicating unit
Electronics module
Basic mounting set
Measuring frame for
mounting
Tachometer
