3.2 Principle of operation
Area of application
VEGAMET 381 Ex is a universal single signal
conditioning instrument with integrated level
switches and display for continuous sensors. At the
same time, it can serve as power supply unit for the
connected sensor.VEGAMET 381 Ex is designed
for connection of any 4 ... 20 mA sensor. The
instrument is suitable for carrier rail, panel and
surface mounting.
Functional principle
The VEGAMET 381 Ex signal conditioning instru-
ment can power connected sensors and process
their measurement signals. The requested param-
eter is shown on the display and also outputted to
the integrated current output for further processing.
Hence the measured signal can be transferred to a
remote indication or a superordinate control sys-
tem. Two level relays for control of pumps or other
devices are also integrated.
