Measuring system
Measuring principle
2-wire loop-powered level transmitter; K-band (24...26 GHz) FMCW radar
Application range
Level measurement of liquids, pastes and slurries
Primary measured value
Δf (change in frequency) between the emitted and received signal
Secondary measured value
Distance, level, volume, mass and reflectivity
Design
Construction
The measurement system consists of a measuring sensor (antenna) and a signal
converter which is only available in a compact version
Options
Integrated LCD display with sun cover (-20..+60°C / -4…+140°F); if the ambient
temperature is not in these limits, the display switches off
2nd current output
PTFE/PP flange plate protection (for Drop antennas without antenna extensions
only)
Distance piece (for process temperature: +150...+200°C / +300...+390°F)
1
Antenna purging system (supplied with a ¼ NPTF connection)
