3.2 Principle of operation
The VEGABAR 61 is a pressure transmitter with isolating diaphragm
for pressure measurement of highly corrosive and hot liquids.
The sensor element for measuring ranges up to 60 bar is the
CERTEC
hydrostatic pressure of the product or the process pressure causes a
capacitance change in the measuring cell via the metal process
diaphragm and the isolating system.
The sensor element for measuring ranges from 100 bar is a wire strain
gauge (DMS) on the rear of the process diaphragm. There, the
process pressure causes a resistance change, which is converted into
an appropriate output signal.

is also used. Dispose of the packaging material via specialised
recycling companies.
Instruments for oxygen applications are sealed in PE foil and provided
with a label "Oxygen! Use no Oil". Remove this foil just before
mounting the instrument! See instruction under "Mounting".
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration

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.

external housing for plics®devices
Information:
The
cable gland can be mounted in three positions each displaced by
90°. Simply exchange the cable gland against the blind plug in the
suitable thread opening.
4 Connect the wire ends as described under "Single/Double
chamber housing" according to the numbering
5 Connect the screen to the internal ground terminal, connect the
outer ground terminal above on the housing to potential equalisation
6 Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable
7 Attach the mounting plate again and tighten the screws
The electrical connection of the sensor to the external housing is
hence ready.

The connection cable is already preconfectioned. If necessary, shorten it to
the requested length, cut the breather capillaries clean. Remove approx.
5 cm of the cable mantle, strip approx. 1 cm insulation from the ends of the
individual wires. After shortening the cable, fasten the type plate with support back onto the cable.
