VEGA VEGAPULS 56V - Manual (Page 10)

10 VEGAPULS 56V
2 Types and versions
VEGAPULS 56 sensors are a new developed
generation of very compact high temperature
radar sensors. For the first time it is now
possible to carry out a non-contact level
measurement under high temperatures and
pressures. They open the advantages of a
radar level measurement for applications
where the special advantages of radar were
formerly not applicable due to the extreme
process conditions.
VEGAPULS 56 radar sensors dominate the
two-wire technology perfectly. They are the
first radar sensors transmitting the supply
voltage and the output signal via one two-
wire line. As output or measuring signal they
operate with an analogue 4␣ …␣ 20␣ mA-output
signal or with a digital output signal. This
operating instruction describes the sensors
with digital output signal.
