Radar level transmitter

Radar level transmitter
Level measurement without contact for liquids and solids
For liquids (max 20m) and solids (max 10m)
Radar pulses W band
Visualization and configuration on a removable display module
Output 4 ÷ 20mA; 2 configurable relays
Remote control via Smartphone


Compact unit with removable programming display, a module for level measurement (W-band) of liquids. RPL75 is available in 4-wire version, with 2 programmable relays on different intervention thresholds and Modbus RTU serial communication. Connection to the 2 “G threaded process made of PP (moplen) for compatibility with chemically aggressive environments. The measuring range is between 0.5 and 20 meters (on liquids) and is guaranteed only in the case of conductive liquids. The polycarbonate housing is equipped with a transparent cover for an immediate reading of the values.
