SITRANS LR140 Radar Level Transmitter

Brand: Siemens AG
Does not ship to United States
SITRANS LR100 series are 80 GHz compact radar transmitters with Bluetooth wireless technology. Featuring a narrow beam for flexible installations in existing vessel openings – or non-intrusively through plastic vessels.

SITRANS LR140 is a 2 wire loop powered radar transmitter for continuous level measurement of liquids and slurries to a range of 8 m (26 ft).
Features
  • Bluetooth connectivity for easy setup with
  • SITRANS mobile IQ.
  • Chemically resistant PVDF sensor.
  • W band FMCW radar yields narrow beam with small antenna for superior performance in short range applications
  • Approved for open air applications outside of a tank.
  • Compact design fits in limited space installations.
