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.

CE conformity
VEGABAR 15 process pressure transmitters meet the protective regulations of EMC
(89/336/EWG) and NSR (73/23/EWG). Conformity has been judged acc. to the following
standards:
EMC Emission EN 50 081 - 1: 1992
Susceptibility EN 50 082 - 2: 1995
NSR EN 61 010 - 1: 1993

Similar to DIN 16 086, reference conditions acc. to IEC 770: Temperature 15°C … 35°C; rel. moisture
45 % … 75 %; pressure 860 mbar … 1060 mbar/86 kPa … 106 kPa
2)
In compensated temperature range from 0°C … +80°C, reference temperature 20°C.
3)
Maintaining the housing protection requires the use of a seal that correctly fits the cable in the cable entry.
If the supplied seal does not fit, a suitable seal must be provided by the customer.
