Liquid and Gas Pressure Transmitter

Application area : The VEGABAR 83 is a pressure transmitter for pressure measurement of gases, vapours and liquids in all industries. The VEGABAR 83 offers special advantages in applications with high pressures. The simple connection of VEGABAR series 80 sensors as electronic differential pressure opens new possibilities for the measurement of differential pressures.
Your benefit

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

Function :
The heart of the pressure transmitter is the completely welded, metallic measuring cell transforming the pressure via the integrated electronics into a standardized output signal.
For measuring ranges up to 40 bar, a piezoresistive sensor element with internal transmission liquid is used. From 100 bar a strain gauge sensor element on the rear of the stainless steel diaphragm is used. This dry system operates without additional isolating liquid.
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.

The pressure transmitter VEGABAR 83 is ideal for level and pressure measurement of liquids and viscous products with high process pressure. With its metallic measuring cell, the instrument delivers excellent measurement accuracy, even under a vacuum.
This pressure transmitter is the first choice for process pressure or level measurement in processes with high pressure, e.g. for

• Circuit pressure measurement in hydraulic pumps
• Pipeline pressure measurement
• Bitumen level measurerment in asphalt mixing plants
• Storage tank level measurement, e.g. for milk in dairies

Materials : The process fitting of the instrument is made of 316L or Alloy C276 (2.4819), the process diaphragm of Alloy C276 (2.4819). FKM, FFKM and EPDM.
Housing versions : The housings are available as single chamber version in plastic, aluminium or stainless steel. They are available in protection ratings up to IP 68 (25 bar) with external electronics as well as in IP 69K.
Electronics versions : Apart from the two-wire electronics with 4 - 20 mA or 4 - 20 mA/ HART, also purely digital versions with Profibus PA, Foundation Fieldbus and are available. In addition a version as Slave sensor is available for the electronic differential pressure measurement.
Adjustment

• Adjustment on the measurement loop : The adjustment of the instrument is carried out via the optional display and adjustment module PLICSCOM or via a PC with the adjustment software PACTware and corresponding DTM.
• Wireless adjustment via Bluetooth : The Bluetooth version of display and adjustment module enables a wireless connection to standard adjustment units. This can be smartphones/tablets with iOS or Android operating system or PCs with PACTware and Bluetooth USB adapter.
