Radar Level Sensor VP31

VEGAPULS 31 is a compact, non-contact radar sensor for continuous level measurement of liquids and bulk solids. It transmits a continuous radar signal via its antenna; the product surface reflects the signal as an echo. The frequency difference between transmitted and received signals is proportional to distance (and thus fill level), which is converted to a corresponding output signal.

Design & materials: Wetted parts are PVDF; the housing is PBT plastic with protection class IP66/IP67.
