3 Product description
VEGAMET 625 • Double channel HART
28970-EN-130701
The order data and the documentation of the instrument can be
retrieved by means of the instrument serial number on the type label.
To do this, "VEGA Tools" and "serial number
search".
3.2 Principle of operation
VEGAMET 625 is a universal signal conditioning instrument for a
number of applications such as level, gauge, interface and process
pressure measurement. At the same time, it can serve as power
supply unit for connected sensors. VEGAMET 625 is designed for
connection of two independent VEGA HART sensors. Hence two
independent measurements can be carried out. By means of a third
measurement loop, the difference between the two input values can
be calculated.
On instruments with one of the optional interfaces (RS232/Ethernet),
the measured values can be retrieved via modem or network and dis-
played by means of a web browser, Visual VEGA or WEB-VV. It is also
possible to send measured values and messages via e-mail. The use
of VEGAMET 625 is particularly suitable for stocktaking, VMI (Vendor
Managed Inventory) and remote enquiry.
The VEGAMET 625 signal conditioning instrument can power two
HART sensors and process their measured signals via the same
cable. The measured value transmission is carried out via a digital
bus system (HART Multidrop). The requested parameter is displayed
and also sent to the integrated current outputs for further processing.
Hence the measured signal can be transferred to a remote indication
or a superordinate control system. Three level relays for control of
pumps or other actuators are also integrated.
Wide-range power supply unit with 20 … 253 V AC/DC for world-wide
use.
Detailed information about the power supply can be found in chapter
"Technical data".
3.3 Adjustment
The instrument can be adjusted with the following adjustment media:
•
With integrated display and adjustment unit
•
an adjustment software according to FDT/DTM standard, e.g.
PACTware and a Windows PC
The entered parameters are generally saved in VEGAMET 625, when
used with PACTware and PC also optionally in the PC.
Information:
When using PACTware and the corresponding VEGA DTM, additional
settings can be carried out which are not possible or only partly pos-
sible with the integrated display and adjustment unit. When using an
adjustment software, you either need one of the integrated interfaces
(RS232/Ethernet) or the interface converter VEGACONNECT.
