VEGABAR 83 Process Pressure Measurement Transmitter (Liquid & Gas)

Product Overview

Pressure Transmitter VEGA VEGABAR 83

Pressure Measurement for Liquids & Gases

VEGA VEGABAR 83 process pressure measurement transmitter with metallic measuring cell can be used to measure liquids and gases at high pressures.

VEGABAR 83 offers special advantages in applications with high pressures as a result of its metallic measuring cell offering high accuracy even under a vacuum and features:

• Maximum dependability and safety through proven technology
• High reliability through vacuum resistant version
• Universal use due to welded measuring cell

The pressure transmitter is ideal for level and pressure measurement of liquids and viscous products with high process pressure in all areas of industry and applications including:

• Gas scrubber
• Turbine steam line
• Raw milk tank
• Ice cream “Premix” mixer
• Jam cooking kettle
• Dissolution of waste paper and cellulose in the pulper

VEGABAR 83 Hazardous Area Certifications

VEGABAR 83 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

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 METEC® is used with temperature ranges up to 200 °C and larger process fittings. This element consists of the ceramic-capacitive CERTEC® measuring cell and a special, temperature-compensated chemical seal system.

Material Transmitter

Available in 316Ti or Alloy C4 (2.4610), the process diaphragm of 316Ti or Elgiloy (2.4711). The process seal is available in FKM, FFKM, EPDM and NBR.
