1.1 Function and configuration

VEGASWING series 80 A vibrating level switches detect the levels of liquids with a viscosity between 0,2 mPa s and

10.000 mPa s and densities ³ 0,5 g/cm3. Their modular design allows them to be used in vessels, tanks and pipelines. T ypical applications involve overfill and dry run protection.

Thanks to its simple and rugged measuring system, VEGASWING can be used in almost any liquid regardless of its chemical and physical properties. It also works well under difficultconditions such as turbulence, air pockets, foam formation, or changes in material, and is insensitive to external vibrations.

VEGASWING with their mechanical connection thread, cone, bolting and flange are also suitable for level detection of liquids in the food processing industr y. The tuning fork and the extension tube are polished for such applications.

For the use in very aggressive products, Hastelloy C4 and coatings ECTFE (Halar) and enamel are used for VEGASWING 81 A and 83 A.

For product temperatures of more than 100°C up to 150°C, VEGASWING 81 A and 83 A can be equipped with a temperature adapter.

Function

The tuning fork is piezoelectrically energised and vibrates at a resonance frequency of approx. 400 Hz. The resonance frequency changes when the tuning fork is covered by the material. This frequency change is detected by the integral oscillator and converted into a switching command.The switching condition (overfill or dry run protection) can be selected using the mode switch.

The oscillator of VEGASWING continuously monitors the instrument for the following faults:

- tuning fork corrosion or damage,

- absence of vibration,

- piezo drive cable malfunction,

- vibrating frequency too low ,

- corrosive medium penetrating the sensor from the vessel.

With a connected signal conditioning instrument (oscillator SWING E82 Z) in addition more functions can be monitored. With oscillator SWING E82 Z and appropriate signal conditioning instrument, the function of the complete measuring chain can be monitored at the touch of a button. This is valid according to the general type approval acc. to WHG as recurring test. More information is provided with the particular signal conditioning instrument.

Should one of the above-mentioned faults occur, or the power supply fails, the electr onics react by switching to a defined switching state, i.e. dependent on the electr onics version

- opening the non-contact switch,

- de-energising the r elay, or

- blocking the output transistor .

With the two-wire output version, the failure is signalled via a defined current to the connected VEGATOR signal conditioning instrument.

Product description

Recurring test acc. to WHG

According to the type approval WHG (Z-65.11-154) the recurring test acc. to WHG can be carried out by pressing a key on the VEGATOR 536 EX, 537 EX, 636 EX signal conditioning instrument. The sensor must not be removed, nor made to respond by filling the vessel. This is valid for VEGASWING 81 A EX and 83 A EX with two-wire SWING E82 Z EX oscillator .

VEGASWING 81 A EX and 83 A EX meet the fail-safe requirements to class 3 (AK 1 … 3) acc. of DIN 19 251 in mode A (overfill protection).

Configuration

A measuring system consists of:

- a VEGASWING with SWING E82 C, SWING E82 R or SWING E82 T oscillator

- external instruments, switched by VEGASWING

- a VEGASWING with SWING E82 Z or SWING E82 Z EX oscillator

- VEGATOR 536 EX, 537 EX or 636 EX signal conditioning instrument or an already mounted instrument, e.g. VEGA TOR 425 EX, 534 EX, 825 EX

- external instruments switched by VEGATOR.

1.2 Approvals

Explosion protection

Only certified VEGASWING 81A EX0, 83A EX0 vibrating level switches should be used in hazardous areas caused by combustible gases, vapours or fog, . VEGASWING 81A EX0, 83A EX0 are suitable for use in hazardous areas zone 1 and zone 0.

The EU-type approval issued by the approval authority is attached to the instruments as proof of explosion protection. Ex-mounting regulations should be noted when VEGASWING 81A EX0, 83A EX0 vibrating level switches are mounted and operated in hazardous areas. The information and conditions of the supplied certificates (EU-type approval, conformity certificate) for VEGASWING 81A EX0, 83A EX0 as well as the appropriate electrical equipment (VEGA TOR signal conditioning instrument, separator , safety barrier) must be taken into account.

• The mounting of Ex-systems must always be carried out by skilled staff.

• VEGASWING 81A EX0, 83A EX0 must be powered by an intrinsically safe circuit; the permissible electrical values are stated in the appropriate Ex-type approval certificate.

• VEGASWING 81A EX0, 83A EX0 with enamelled tuning fork or plastic parts acquiring static electricity have a warning label stating the measures to be taken to avoid dangers due to electrostatic discharges. The contents of the warning label should be noted.

• The explosion protection of the electrical equipment used is only ensured when the limit temperatures stated in the certificate are not exceeded.

• In the case of dangers due to oscillation and vibrations, the appropriate parts of VEGASWING 83A EX0 should be secured effectively against these dangers.

Overfill protection

The information and conditions of the supplied general type approvals must be noted when a VEGASWING is used as part of an overfill protection for vessels storing water endangered liquids. The general type approval should be available at the place of installation place. VEGASWING should only be used in liquids against which the materials of the wetted parts of VEGASWING are sufficiently chemically resistant.
