VEGA VEGAWELL 52 Hydrostatic Level Sensor

Product Overview

Level Sensor VEGA VEGAWELL 52

Level Measurement for Liquids (+abrasive content)

VEGA VEGAWELL 52 hydrostatic level sensor is a submersible pressure transmitter for continous level measurement of liquids.

VEGAWELL 52 level sensor is versatile thanks to a robust construction and clever cable design.

VEGAWELL 52 features a high plant availability as a result of an integrated overvoltage protection and a high reliability thanks to maximum overload and vacuum resistance of the ceramic measuring cell.

VEGA VEGAWELL 52 submersible pressure transmitter is specified for level measurement of water/wastewater in tanks on ships. 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.

• flow measurement i.e. overflow measurement on weirs
• water level measurement for control of groundwater pumps
• level measurement in ballast water tanks on ships
• level measurement in oil tanks

VEGAWEll 52 Level Sensor Hazardous Area Certifications

VEGAWELL 52 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, 2G Ex ia IIC T6

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

IEC Ex ia IIC T6 Ga, Gb

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 VEGAWELL 52 level sensor via the display and adjustment module or processed via the signal output.
