Further application possibilities are also the use as X-ray alarm or real value correction.If X-ray alarm is selected, the instrument detects radiation from exter-nal sources. Possible external radiation sources can be, for example, aweldjointtestinaneighbouringfacilityorotherradiation-basedinstruments.When the instrument operates as real value correction it transmits the real value to correct another radiation-based sensor. The measure-ment can thus be adapted perfectly to the situation in the vessel.

In radiation-based measurement, a Caesium-137 or Cobalt-60 iso-topeemitsfocussedgammaraysthatareattenuatedwhenpenetrat-ingthetubewallandthemedium.TheNaIdetectorontheoppositeside, on a pipeline for example, receives the radiation. The intensity of the radiation is dependent on the density of the measured media.

3.3 Packaging, transport and storageYourinstrumentwasprotectedbypackagingduringtransport.Itscapacity 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 under 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-cealeddefectsmustbeappropriatelydealtwith.

Up to the time of installation, the packages must be left closed and stored according to the orientation and storage markings on the outside.Unlessotherwiseindicated,thepackagesmustbestoredonlyunderthefollowingconditions:

• 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 partsThe display and adjustment module PLICSCOM is used for measured value indication, adjustment and diagnosis. It can be inserted into the sensor or the external display and adjustment unit and removed at any time.Youcanfindfurtherinformationintheoperatinginstructions"Display and adjustment module PLICSCOM" (Document-ID 27835).

4.1 General instructionsThe source container is part of the measuring system. In case the sourcecontainerisalreadyequippedwithanactiveisotope,thesource container must be locked before mounting.

Danger:Before mounting; make sure that the source is securely closed. Use a padlock to secure the source container in the closed condition and prevent it from being inadvertently opened.

Protectyourinstrumentthroughthefollowingmeasuresagainstmoisture penetration:

• Use the recommended cable (see chapter "Connecting to power supply")

• Tighten the cable gland• LooptheconnectioncabledownwardinfrontofthecableglandThis applies particularly to:

• outdoor mounting• installationsinareaswherehighhumidityisexpected(e.g.through

cleaning processes)• installations on cooled or heated vessels

Make sure that all parts of the instrument exposed to the process are suitable for the existing process conditions.These are mainly:

• Active measuring component• Processfitting• Process seal

Process conditions are particularly:

• Process pressure• Process temperature• Chemical properties of the medium• AbrasionandmechanicalinfluencesYoucanfindthespecificationsinchapter"Technical data" and on the nameplate.

Density measurementA density and concentration measurement is possible on pipelines and vessels. The accuracy of the measurement increases in propor-tion to the radiated length (L) of medium.
