VEGABAR 82 Process Pressure Measurement Transmitter (Liquid & Gas)

Product Overview

Pressure Transmitter VEGA VEGABAR 82

Pressure Measurement for Liquids & Gases

VEGA VEGABAR 82 process pressure measurement transmitter with ceramic measuring cell can be used to measure liquids gases and vapours.

VEGABAR 82 can easily deal with substances such as sand as a result of the highly resistant ceramic measuring cell.

VEGABAR 82 offers maximum reliability and can be used successfully in all industries and features:

• Low maintenance costs thanks to wear-free ceramic measuring cell
• High plant availability through maximum overload and vacuum resistance of the ceramic measuring cell
• Small measuring range for higher accuracy

The versatile pressure transmitter handles temperatures up to 150° C and covers 80% all application in the process industry as well as the below applications:

• Grit washer
• Gas pipeline
• Biogas storage facility
• Pressure in drinking water pipelines
• Tanks for solvents
• Primary reformer

VEGABAR 82 Hazardous Area Certifications

VEGABAR 82 process pressure measurement transmitter 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

VEGA process pressure measurement transmitters are suitable for use in hazardous areas and their instruments also have various ship approvals e.g according to GL, LRS or ABS.

Measuring Cell Technology

The main part of the pressure transmitter is the ceramic measuring cell that cleverly transforms the pressure into an electrical signal.

The pressure dependent signal is changed by the integrated electronics into a standard signal output. The sensor element with VEGABAR 82 is the CERTEC® measuring cell with excellent long-term stability, high overload resistance and available with a temperature sensor.

Material Transmitter

Available in 316L, PVDF, Alloy, C4-plated or Sapphire-ceramic®. The process seal is available in FKM, FFKM as well as EPDM.

Housing Versions

Pressure Transmitter Applications

♦ Sewage Pump Monitoring – VEGABAR 82 provides pressure measurement in sewage pipes. Benefits:

• resistant to vibrations and abrasions
• high resistance to vacuum or pressure shocks
• front-flush diaphragm stops build up
• self-monitoring ceramic measuring cell

♦ Pressure Measurement in Batch Vessels – Two VEGABAR 82 pressure transmitters are able to provide accurate level and gauge in batch vessels for the Pharmaceutical Industry. Benefits:

• front-flush diaphragm stops build up
• double seal increases dependability
• vacuum and overload resistant
• self-monitoring ceramic measuring cell

♦ Paper Mill Level Measurement – VEGABAR 82 can be installed in the bleaching tower of a paper mill which is able to prevent the discharge pump from running dry. Benefits:

• self-monitoring ceramic measuring cell
• simple installation and removal as draining of the bleaching tower isn’t required
• resistance to abrasion and hydraulic shocks
• front flush installation

♦ Pressure Monitoring in a Vacuum in a Distillation Column – VEGABAR 82 enables energy to be saved and product productivity to be high even when operating under a high vacuum. Benefits:

• double seal increases dependability
• dry ceramic measuring cell
• ability to measure up to absolute vacuum
