VEGA VEGAFLEX 86 Guided Wave Radar Level Sensor

Product Overview

Level Sensor VEGA VEGAFLEX 86

VEGA VEGAFLEX 86 guided wave radar level sensor provides continuous level and interface measurement for many liquids including applications with vapour buildup, foam or condensation.

VEGAFLEX 86 level sensor features a shortenable specialised probe ensuring density-independent measurement, simple standardisation and high flexibility in the planning. and a simple set up providing reliable and accurate level and interface measurements.

The proven mechanical construction and intricate diagnostics of the level sensor ensures a maintenance free operation for any type of liquid in demanding environments in sectors such as the chemical, petrochemical, energy and oil and gas.

Applications include:

• Steam boiler
• Distillation column
• Heat recovery boiler
• Steam drum

VEGA level sensors are suitable for use in hazardous areas and their instruments also have various ship approvals such as e.g. DNV, GL, LRS or ABS.

FunctioN

High frequency microwave pulses are coupled onto a cable or rod and guided along the probe. The pulse is reflected by the product surface. The time from emission to reception of the signals is proportional to the level in the vessel.

Materials

The wetted parts of the instrument are made of stainless steel and the instrument seal is made of one of the following FKM, FFKM or EPDM.

Housings

The level sensor housings are available as double chamber version in plastic, stainless steel or aluminium with protection ratings up to IP66/IP67.

Electronics

VEGA sensors are available in different electronics versions. Apart from the two-wire electronics with 4 … 20 mA/HART, there are two pure digital versions with Profibus PA and Foundation Fieldbus possible as well as one version for connection to a signal conditioning instrument.

Signal Output

• Profibus PA
• Foundation Fieldbus
• Two-wire 4 … 20 mA/HART®
• Modbus
• Four-wire 4 … 20 mA/HART®

Approvals

• ATEX
• IEC
• FM
• CSA
• Gost
• Overfill protection
• Ship
• SIL2

VEGA LEVEL SENSORS – veGAFLEX

VEGAFLEX level sensors provide level measurement for bulk solids, liquids and separation layers (interfaces). In guided wave radar level measurement, microwave pulses are conducted along a cable or rod probe and reflected by the product surface. The measuring probe of the TDR sensor ensures that the signal reaches the medium without disruption. VEGA is a global manufacturer of process and hazardous area instrumentation.
