Principle of operation

Application area
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 inst-
rument can power connected sensors and pro-
cess their measurement signals. The requested
measured variable is shown on the display and
also outputted to the integrated current output
for further processing. The measurement signal
can thus be transferred to a remote indication or
a superordinate control system. Two level relays
for control of pumps or other devices are also
integrated.
Voltage supply
Wide range power supply unit with
20 ... 253 V AC/DC for worldwide use.
