Product catalog summary
Overview
The VEGABAR 18 is a pressure sensor designed for reliable measurement of gases, vapors, and liquids. It features a two-wire 4 to 20 mA output and a ceramic measuring cell for enhanced process safety and plant operation.

Key Benefits
  • Cost-effective with compact mounting dimensions.
  • High plant availability due to maximum overload and vacuum resistance.

Functionality
The sensor converts pressure into an electrical signal using a ceramic CERTEC® measuring cell, known for its long-term stability and overload resistance.

Technical Specifications
  • Measuring Ranges: -1 to +25 bar (-14.5 to +300 psig).
  • Smallest Measuring Range: +0.1 bar (+1.45 psig).
  • Deviation: Less than 0.5%.
  • Output Signal: 4 to 20 mA.
  • Process Fitting: Thread from G½, ½ NPT.
  • Temperature Range: Process -40 to +100 °C, Ambient -40 to +70 °C.
  • Operating Voltage: 12 to 35 V DC.

Materials and Housing
  • Wetted parts made of 316L and sapphire-ceramic®.
  • Process seal available in FKM.
  • Housing with plug connectors per ISO 4400 or M12 x 1, protection ratings up to IP66/IP67.

Electrical Connection
Wiring plans are provided for two-wire 4 to 20 mA connections using M12 x 1 plug and ISO 4400 plug.

Dimensions
Detailed dimensions are provided for various thread types including G½ and ½ NPT.

The process seal is available in FKM. You will find a complete overview of the available materials and seals in the "Configurator" at www.vega.com and "VEGA Tools". Application area Housing versions The pressure transmitter VEGABAR 18 ensures reliable plant operation and improved process safety by accurately measuring the measured values of gases, vapours and liquids. The housing is equipped with plug connectors acc. to ISO 4400 or M12 x 1. It is available with protection ratings up to IP66/IP67. Your benefit Electronics versions • Low-cost version with very small mounting dimensions The instrument has a 4 … 20 mA signal output. • High plant availability through maximum overload and vacuum resistance of the ceramic measuring cell Electrical connection Function The heart of the pressure transmitter is the pressure measuring cell transforming the pressure into an electrical signal. This pressuredependent signal is convereted by the integrated electronics into a standardized output signal. Sensor element is the ceramic CERTEC® measuring cell with excellent long-term stability and high overload resistance. Wiring plan - two-wire 4 … 20 mA - M12 x 1 plug 1 Voltage supply and signal output Wiring plan - two-wire 4 … 20 mA - plug according to ISO 4400 1 Voltage supply and signal output You can find details on electrical connection in the instrument operating instructions at www.vega.com/downloads.
