VEGA VEGABAR 86 Hydrostatic Level Sensor

Product Overview

Level Sensor VEGA VEGABAR 86

Level Measurement for Liquids (+abrasive content)

VEGA VEGABAR 86 hydrostatic level sensor is a submersible pressure transmitter for level measurement in wells, basins and open vessels.

VEGABAR 86 level sensor features great flexibility and low maintenance levels due to the wear-free ceramic measuring cell.

VEGABAR 86 features a self-cleaning effect through the front-flushing installation and a high plant availability through maximum overload and vacuum resistance of the ceramic measuring cell.

VEGA VEGABAR 86 submersible pressure transmitter is specified for level measurement of water, acids, alkalis and chemically aggressive liquids. Submersible sensor provides accurate water level measurement in the wastewater industry and hazardous area level measurement in the oil, gas, chemicals and food processing industries.

• chemically stable level measurement sensor and transmitter for use in ultrapure water
• water level measurement with two suspension pressure transmitters for lock control
• maintenance free level measurement sensor in waste water shafts

VEGABAR 86 Level Sensor Hazardous Area Certifications

VEGABAR 86 hydrostatic level sensor is available with hazardous area certifications to meet ATEX & IECEx directives for Zone 1 and Zone 2 installations.

ATEX & IECEx Approvals

ATEX II 1G, 1/2G, 2G Ex ia IIC T6

ATEX II 1G, 1/2G, 2G Ex ia IIC T6 + Ship Approval

ATEX II 1/2G, 2G Ex d IIC T6

IEC Ex ia IIC T6

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.

Measuring Cell Technology

The pressure of the measured medium acts on the pressure measuring cell, converting this pressure into an electronic signal.

The sensor element is the ceramic CERTEC measuring cell with front-flush, abrasion-resistant ceramic diaphragm – the CERTEC measuring cell is equipped with a temperature sensor and the temperature value can be displayed on the VEGA VEGABAR 86 level sensor via the display and adjustment module or processed via the signal output.

Pressure Transmitter Applications

♦ Purified Water Level Measurement – VEGABAR 86 is suitable for providing level measurement in purified water thanks to the sensor having protection from a PVDF body and a ceramic measuring cell Benefits:

• up to 80° Celsius temperature application
• metal-free materials provide stability
• further dependability thanks to double seal

♦ Sluice Level Measurement – Two VEGABAR 86’s are installed either side of the slice basin to control the levels inside. Benefits:

• corrosion resistant
• front-flush diaphragm
• self-monitoring ceramic measuring cell

♦ Sewage Shaft Level Measurement – VEGABAR 86 allows maintenance free detection of the water level in a sewage shaft Benefits:

• corrosion resistant
• no build up or additional residue
• front-flush and abrasion resistant ceramic measuring cell
