3.2 Principle of operation
VEGABAR 64 is a pressure transmitter for use in the paper, food
processing and pharmaceutical industries as well as in water/sewage
water plants. Depending on the version, it is used for level, gauge,
absolute pressure or vacuum measurement. Measured products are
gases, vapours and liquids, also those containing abrasive substances.
The sensor element is the CERTEC
abrasion resistant ceramic diaphragm. The hydrostatic pressure of the
medium or the process pressure causes a capacitance change in the
measuring cell via the diaphragm. This change is converted into an
appropriate output signal and outputted as measured value.
The CERTEC
sensor. The temperature value can be displayed via the indicating and
adjustment module or processed via the signal output.
Power is supplied via the H1 Fieldbus. A two-wire cable according to
Fieldbus specification serves as carrier of both power and digital data
for multiple sensors. This cable can be operated in two versions:
l via an H1 interface card in the control system and additional power
supply

4.1 General ins
Make sure that all parts of the instrument in contact with the measured
product, especially the sensor element, process seal and process
fitting, are suitable for the existing process conditions such as process
pressure, process temperature as well as the chemical properties of
the medium.
You can find the specifications in chapter "Technical data" in the or on
the type label.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

The instrument requires a operating voltage of 9 … 32 V DC.
Operating voltage and the digital bus signal are carried on the same
two-wire connection cable. Power is supplied via the H1 power supply.
Connection is carried out with screened cable according to Fieldbus
specification.
Use cable withround cross-section. A cable outer diameter of 5 … 9 mm
(0.2 … 0.35 in) ensures the seal effect of the cable gland. If you are
using cable with a different diameter or cross-section, exchange the
seal or use a suitable cable gland.
Make sure that the entire installation is carried out according to the
Fieldbus specification. In particular, make sure that the termination of
the bus is done with appropriate terminating resistors.

In systems with potential equalisation, connect the cable screen

In systems without potential equalisation, connect

In the connection box or T-distributor, the screen of the short stub to

cable screen. The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g. 1 nF, 1500 V). The low

protective effect against high frequency interference signals remains.
