l Article numbers documentation
With the serial number, you can access the delivery data of the
instrument via www.vega.com, "VEGA Tools" and "serial number
search". In addition to the type label outside, you can also find the
serial number on the inside of the instrument.
3.2 Principle of operation
VEGABAR 63 is a pressure transmitter for measurement of over-
pressure, absolute pressure or vacuum. Measured products are
gases, vapours and liquids in measuring ranges up to 4000 bar
(400 MPa); with front-flush version also viscous liquids in measuring
ranges up to 600 bar (60 MPa).
The process pressure acts on the sensor element via the stainless
steel diaphragm. The process pressure causes a resistance change
which is converted into a corresponding output signal and outputted as
measured value.
1)
Power supply via the Profibus DP/PA segment coupler or VEGALOG
571 EP cards. A two-wire cable according to Profibus specification
serves as carrier of both power and digital data transmission for
multiple sensors. The instrument profile of VEGABAR 63 corresponds
to profile specification version 3.0.
The GSD (instrument master files) and bitmap files necessary for
planning your Profibus-DP-(PA) communication network are available
from the download section on the VEGA homepage www.vega.com
under "Services - Downloads - Software - Pro
fibus". There you can
also find the appropriate certificates. In a PDM environment, an EDD
(Electronic Device Description) is also required to enable the full range
of sensor functions (also available as a download).A CD with the
appropriate files can be ordered via e-mail under [email protected] or
by phone from one of the VEGA agencies under the order number
"DRIVER
.S".
The backlight of the indicating and adjustment module is powered by
the sensor. Prerequisite is a certain level of operating voltage.
The data for power supply are specified in chapter "Technical data".
The optional heating requires its own power supply. You can find
further details in the supplementary instructions manual "Heating for
indicating and adjustment module".
This function is generally not available for approved instruments.
1) Measuring ranges up to 16 bar: piezoresistive sensor element with internal
transmission liquid, with measuring ranges up to 25 bar: Strain gauge
(DMS) sensor element on the rear of the stainless steel diaphragm (dry).
