Product description

29271-EN-070116

It is designed for industrial use in all areas of process

technology and is preferably used for bulk solids.

Typical applications are overﬁll and dry run protection.Thanks

to its simple and robust measuring system,VEGAVIB 62 is

virtually unaﬀected by the chemical and physical properties of

the bulk solid.

It functions even when exposed to strong external vibration or

changing products.

Solid detection in water

IfVEGAVIB 62 was ordered for solid detection in water,the

vibrating rod is to the density of water.In air or if covered by

water (density:1g/cm³/0.036 lbs/in)VEGAVIB 62 signals

uncovered.Only if the vibrating element is also covered with

solids (e.g.sand,sludge,gravel etc.) will the sensor signal

covered.

Fault monitoring

The electronics of VEGAVIB 62 continuously monitors the

following criteria:

lCorrect vibrating frequency

lLine break to the piezo drive

If one of the stated malfunctions is detected or in case of

power failure,the electronics takes on a deﬁned switching

condition,i.e.the relay deenergises (safe condition).

The vibrating rod is piezoelectrically energised and vibrates at

its mechanical resonance frequency of approx.360 Hz.When

the vibrating rod is submerged in the product,the vibration

amplitude changes.This change is detected by the integrated

oscillator and converted into a switching command.

VEGAVIB 62 is a compact instrument,i.e.it can be operated

without external evaluation system.The integrated electronics

evaluates the level signal and outputs a switching signal.With

this switching signal,a connected device can be operated

directly (e.g.a warning system,aPLC,a pump etc.).

The data for power supply are stated in chapter "Technical

data"in the "Supplement".

3.3Operation

With the factory setting,products with a density of >0.05 g/cm³

(0.002 lbs/in³)can be measured.It is possible to adapt the

instrument for products with lower density >0.02 g/cm³

(0.0007 lbs/in³).

On the electronics module you will ﬁnd the following indicating

and adjustment elements:

lsignal lamp for indication of the switching condition (green/

red)

lpotentiometer for adaptation to the product density

lMode switch for selecting the switching condition (min./

max.)

3.4Storage and transport

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.In addition,the sensor is

provided with a protective cover of cardboard.For special

versions PE foam or PE foil is also used.Dispose of the

packaging material via specialised recycling companies.

lStorage and transport temperature see "Supplement -

Technical data -Ambient conditions"

lRelative humidity 20 …85 %

4Mounting

4.1General instructions

In general,VEGAVIB 62 must be mounted vertically.The

instrument must be mounted in such a way that the vibrating

element is at the height of the requested switching point.

Use the recommended cables (see chapter "Connecting to

power supply")and tighten the cable gland.

You can give your VEGAVIB 62 additional protection against

moisture penetration by leading the connection cable down-

ward in front of the cable entry.Rain and condensation water

can thus drain oﬀ.This applies mainly to mounting outdoors,in

areas where moisture is expected (e.g.by cleaning processes)

or on cooled or heated vessels.

Fig.2:Measures against moisture penetration

Do not hold VEGAVIB 62 on the vibrating element.Especially

with ﬂange and tube versions,the sensor can be damaged by

the weight of the instrument.

Remove the protective cover just before mounting.

The process ﬁtting must be sealed if there is gauge or low

pressure in the vessel.Before use,check if the seal material is

resistant against the measured product and the process

temperature.

The max.permissible pressure is stated in chapter "Technical

data"in the "Supplement"or on the type label of the sensor.

The vibrating level switch is a measuring instrument and must

be treated accordingly.Bending the vibrating element will

destroy the instrument.
