Safety information
Please read this manual carefully, and also take
note of country-specific installation standards
(e.g. the VDE regulations in Germany) as well
as all prevailing safety regulations and accident prevention rules.
For safety and warranty reasons, any internal
work on the instruments, apart from that involved in normal installation and electrical connection, must be carried out only by qualified
VEGA personnel.

1.1 Function and configuration
VEGABAR 15 is a process pressure transmitter with a piezoresistive sensor element for
pressure measurement of gas, steam or
liquids between 1 bar and 600 bar (relative
pressure). For use in dense, non-uniform and
cristallizing products, a version with flush
diaphragm is available. A standardised
4 … 20 mA current signal is available as
output signal.
