3.2 Principle of operationThe VEGACAP 67 is a point level sensor for bulk solids. The probe is designed for high temperature applications.

Probe, measured product and vessel wall form an electrical capacitor. Thecapacitanceisinfluencedbythreemainfactors.

Fig. 3: Functional principle - Plate capacitor1 Distance between the electrode surfaces2 Size of the electrode surfaces3 Type of dielectric between the electrodes

The probe and the vessel wall are the capacitor plates. The measured product is the dielectric. Due to the higher dielectric constant of the product compared to air, the capacitance increases as the probe is gradually covered.The capacitance change is converted by the electronics module into a switching command.

Depending on your requirements, VEGACAP 67 with two-wire elec-tronicscanbeconnectedtodifferentsignalconditioninginstruments.Compatible signal conditioning instruments are listed in chapter "Technical data".Thedataforpowersupplyarespecifiedinchapter"Technical data".

3.3 OperationThe probe can be adapted to the dielectric constant of the product directly on the electronics module.A switching command can be triggered when the probe is covered or laid bare.Ontheelectronicsmoduleyouwillfindthefollowingdisplayandadjustment elements:

• Control lamp for indication of the device status.

3.4 Packaging, transport and storageYour 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

• Storageandtransporttemperatureseechapter"Supplement - Technical data - Ambient conditions"

• Relative humidity 20 … 85 %

4.1 General instructionsMake sure that all parts of the instrument coming in direct contact with the process, especially the sensor element, process seal and processfitting,aresuitablefortheexistingprocessconditions,suchas process pressure, process temperature as well as the chemical properties of the medium.Youcanfindthespecificationsinchapter"Technical data"andonthenameplate.

In general, VEGACAP 67 must be mounted vertically. The instrument must be mounted in such a way that the probe is at the height of the requested switching point.

Before beginning the welding work, remove the electronics module from the sensor. By doing this, you avoid damage to the electronics through inductive coupling.Ground the probe before welding directly on the rod or cable.

With threaded versions, the housing must not be used to screw in the instrument. Applying tightening forces on the housing can damage its internal parts.Use the hexagon for screwing in.

Usetherecommendedcables(seechapter"Connecting to power supply")andtightenthecablegland.You can give your instrument additional protection against moisture penetration by leading the connection cable downward in front of the cableentry.Rainandcondensationwatercanthusdrainoff.Thisap-plies mainly to outdoor mounting as well as installation in areas where highhumidityisexpected(e.g.throughcleaningprocesses)oroncooled or heated vessels.

Metal vesselMake sure that the mechanical connection of the probe to the vessel iselectricallyconductivetoensuresufficientgrounding.Use conductive seals, such as those made of copper or lead, etc. Insulatingmeasures,suchascoveringthethreadwithTeflontape,can interrupt the necessary electrical connection with metal vessels. For this reason, ground the probe on the vessel or use a conductive seal material.Non-conductive vesselsIn non-conductive vessels, e.g. plastic tanks, the second pole of the capacitor must be provided separately.

Metric threadsIn 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 threadIn 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.

4.2 Mounting instructionsDuetotheeffectsofagitators,equipmentvibrationorsimilar,thelevelswitch can be subjected to strong lateral forces. For this reason, do not use an overly long electrode for VEGACAP 67, but check if you canmountashortlevelswitchonthesideofthevesselinhorizontalposition.

Iftheinstrumentismountedinthefillingstream,unwantedfalsemeasurement signals can be generated. For this reason, mount the instrument at a position in the vessel where no disturbances, e.g. from fillingopenings,agitators,etc.,canoccur.This applies particularly to instrument versions with a longer probe.

The probe should protrude into the vessel to avoid buildup. For that reason,avoidusingmountingbossesforflangesandscrewedfittings.This applies particularly to use with adhesive products.

In silos with bulk solids, material cones can form which change the switching point. Please keep this in mind when installing the sensor in the vessel. We recommend selecting an installation location where the probe detects the average value of the material cone.The probe must be mounted in a way that takes the arrangement of thefillingandemptyingaperturesintoaccount.To compensate measurement errors caused by the material cone in cylindrical vessels, the sensor must be mounted at a distance of d/6 from the vessel wall.

Warning:Connect only in the complete absence of line voltage.

• The electrical connection must only be carried out by trained personnel authorised by the plant operator.

• Alwaysswitchoffpowersupply,beforeconnectingordisconnect-ing the instrument.

Inhazardousareasyoumusttakenoteoftherespectiveregulations,conformityandtypeapprovalcertificatesofthesensorsandpowersupply units.

Connect the voltage supply according to the following diagrams. Take note of the general installation regulations. As a rule, connect VE-GACAP67tovesselground(PA),orincaseofplasticvessels,tothenext ground potential. On the side of the instrument housing there is a ground terminal between the cable entries. This connection serves todrainoffelectrostaticcharges.InExapplications,theinstallationregulationsforhazardousareasmustbegivenpriority.Thedataforpowersupplyarespecifiedinchapter"Technical data".

The instrument is connected with standard two-wire cable without screen. If electromagnetic interference is expected which is above the test values of EN 61326 for industrial areas, screened cable should be used.Use cable with round cross-section. A cable outer diameter of 5…9mm(0.2…0.35in)ensuresthesealeffectofthecablegland.Ifyouareusingcablewithadifferentdiameterorcross-section,exchange the seal or use a suitable cable gland.Inhazardousareas,useonlyapprovedcableconnectionsforVE-GACAP 67.

Take note of the corresponding installation regulations for Ex applica-tions.
