3.2Principle of operation
VEGABAR 53 is a pressure transmitter for measurement of
gauge pressure,absolute pressure or vacuum.Measured
products are gases,vapours and liquids up to 600 bar.With
flush version also viscous liquids.
The process pressure acts via the stainless steel diaphragm to
the sensor element1).Aresistance change is caused which is
converted into a respective output signal and outputted as
measured value.
Power supply is via the Profibus DP/PA segment coupler or
VEGALOG 571 EP cards.Atwo-wire cable acc.to Profibus
specification serves as carrier of both power and digital data
signals for multiple sensors.The instrument profile of
VEGABAR 53 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 –Profibus".There you can also find the appropriate
certificates.InaPDM environment,an EDD (Electronic Device
Description)is also required to enable the full range of sensor
functions (also available as a download).ACDwith the
appropriate files can be ordered via e-mail under info@de.
vega.com or by phone from one of the VEGA agencies under
the order number "DRIVER.S".
3.3Adjustment
VEGABAR 53 can be adjusted with three different adjustment
media:
lthe indicating and adjustment module PLICSCOM
lwith the suitable VEGA DTM in conjunction with an
adjustment software acc.to FDT/DTM standard,e.g.
PACTware™and PC
lthe Simatic adjustment program PDM
The entered parameters are generally saved in VEGABAR 53,
optionally also in PLICSCOM or in PACTware™.
1)For meas.ranges up to 16 bar:piezoresistive sensor element with internal
transmission liquid,for meas.ranges from 25 bar:strain gauge (DMS)
sensor element on the rear of the stainless steel diaphragm (dry).
