VEGAPULS 56K
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. An analogue 4 ... 20 mA-output signal is
available as output or measuring signal.
