Safety information

Please read this manual carefully, and also take

note of country-specific installation standards

(e.g. the VEGA regulations in Germany) as well

as all prevailing safety regulations and acci-

dent prevention rules.

For safety and warranty reasons, only quali-

fied VEGA personnel must carry out any inter-

nal work on the instruments, apart from that

involved in normal installation and electrical

connection.

Note Ex area

Please note the attached safety instructions,

containing important information on installation

and operation in Ex areas.

These safety instructions are part of the oper-

ating instructions manual and come with the Ex

approved instruments.

Product description

1 Product description

VEGASWING 61 and 63

VEGASWING 61/63 vibrating level switches

are used for level detection of liquids.

Typical applications are overfill and dry run

protection. Using a tuning fork with a length

of only 40 mm, VEGASWING 61 opens up

new areas of application, e.g. in pipelines

from DN 25. Power supply and output signal

correspond to the Namur interface acc. to

IEC 60947-5-6 (EN 50227).

VEGASWING series 60 vibrating level

switches detect levels of liquids with a vis-

cosity of 0.1 … 10.000 mPa s and a density

of ≥0.5 g/cm3. Modular construction enables

their use in vessels, tanks and pipelines.

Thanks to its simple and rugged measuring

system, VEGASWING is virtually unaffected

by the chemical and physical properties of

the liquid. It does its job even under unfa-

vourable conditions such as turbulences, air

bubbles, foam generation, buildup, strong

external vibration or constantly changing

products.

• Tuning fork with only 40 mm length.

• Thread from ¾ and flanges from DN 25

(ANSI 1").

• Process temperature -50°C ... +250°C

without shock limitation.

• Insensitive to external vibration.

• Process pressure up to 64 bar.

• Also ECTFE or PFA coated or enamelled.

• Viscosity 0.1 ... 10000 mPa s.

• Density range 0.5 g/cm3… 2.5 g/cm3.

• NAMUR output.

• Ex-Zone 0/1

• Overfill protection acc. to WHG.

• Integrated fault monitoring.

• Fixed, exactly reproducible switching

point.

• Switching point visible with closed instru-

ment (LED).

• Set-up without adjustment.

• Installation in any position.

• Min. or max. mode.

Function and application

2 Function and application

2.1 Principle of operation

VEGASWING vibrating level switches detect

levels in almost all liquids.

Viscosity: 0.1 ... 10.000 mPa s

Density: 0.5 ... 2.5 g/cm3

VEGASWING measuring principle

The tuning fork is piezoelectrically energised

and vibrates at its mechanical resonance

frequency of approx. 1200 Hz. The piezo-

electric elements are fastened mechanically

and are therefore not subject to temperature

shock limitations. When the tuning fork is

submerged in the product, the frequency

changes. This change is detected by the

integrated oscillator and converted into a

switching command.

The integrated fault monitoring detects:

- interruption of the connection cable to the

piezoelectric elements

- extreme wear on the tuning fork

- break of the tuning fork

- absence of vibration.

In case of failure, a defined current

(≤1.0 mA) is impressed on the cable to the

NAMUR amplifier.

Compact instrument with NAMUR

output

The oscillator delivers as output signal a

current jump acc. to IEC 60947-5-6. The

switching signal is further processed via

complementary NAMUR processing sys-

tems, e.g. PLC input card or remote I/O.

2.2 Measuring system

Level detection of liquids with NAMUR

compact instrument

Measuring system with VEGASWING as NAMUR

compact instrument

A measuring system consists of:

- a VEGASWING vibrating level switch with

integrated oscillator SW E60N

- a NAMUR amplifier acc. to IEC 60947-5-6

(EN 50 227 / DIN 19 234).
