causes a capacitance change in the measuring cell via the
ceramic diaphragm. This change is converted into an
appropriate output signal.

measured value transmission on the same cable.
The supply voltage range can differ depending on the
instrument version.
Data for power supply are specified in chapter "Technical
data".
3.3 Operation
VEGAWELL 51 with 4 … 20 mA electronics has no adjustment
option.
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 environ-
ment-friendly, recyclable cardboard. For special versions, PE
foam or PE foil is also used. Dispose of the packaging material
via specialised recycling companies.

Transport inspection
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.
