3.2Principle of operation
VEGAMET 381 Ex is a universal single signal conditioning
instrument with integrated level switches and display for
continuously measuring sensors.At the same time,it can
serve as power supply unit for connected sensors.VEGAMET
381 Ex is designed for connection of an individual 4…20 mA
sensor.The instrument is suitable for carrier rail,panel and
surface mounting.
The VEGAMET 381 Ex signal conditioning instrument can
power connected sensors and process their measured
signals.The requested parameter is displayed and outputted
in addition to the integrated current output for further
processing.Hence the measured signal can be transferred to
a remote indication or a superordinate control system.Two
level relays for control of pumps or other actors are also
integrated.
Wide-range power supply unit with 20 …253 VAC/DC for
world-wide use.
You can find detailed information on the power supply in the
"Technical data"in the "Supplement".
3.3Operation
The adjustment of VEGAMET 381 Ex is carried out via the
integrated keys and a 16-step function switch.
3.4Storage and transport
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.
