SITRANS LR120 Radar Level Transmitter

Brand: Siemens Aktiengesellschaft

Free Shipping on Orders Over $500.00 CAD

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 LR120 is a compact radar transmitter for continuous level measurement of liquids and solids to a range of 30 m (98.4 ft).
Features
  • Bluetooth connectivity for easy setup with SITRANS mobile IQ
  • Chemically resistant PVDF enclosure
  • HART 7.0 or Modbus RTU communication for intelligent integration into your application
  • W band FMCW radar yields narrow beam with small antenna for superior performance in applications with obstructions
  • Approved for open air applications outside of a tank
  • 2 mm accuracy and zero near range distance yields optimum inventory management capability
  • Submergence shield accessory prevents build up on sensor during flooding conditions
  • Hazardous area variants available for safe use in explosive gas or dust environments
