3.2 Principle of operation

VEGABAR 17 is a pressure transmitter for measurement of gauge
pressure, absolute pressure or vacuum. Measured products are
gases, vapours and liquids. The front flush versions are also suitable
for use in viscous or contaminated products.
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)
4 ... 20 mA two-wire electronics for voltage supply and measured
value transmission on the same cable.
3.3 Operation
The VEGABAR 17 has no adjustment options.
However, there are two built-in potentiometers for recalibration of zero
and span.
3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE foil
is also used. Dispose of the packaging material via specialised
recycling companies.
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:
