SITRANS LR120 is a compact radar transmitter for continuous level measurement of liquids and solids to a range of 30 m (98.4 ft).

Benefits:

Bluetooth connectivity for easy setup with SITRANS mobile IQ
Chemically resistant PVDF enclosure
HART 7.0 or Modbus RTU (in preparation) 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

Application:

SITRANS LR120 is a W band FMCW radar level transmitter, packaged in a hermetically sealed PVDF enclosure for years of trouble-free reliable measurement service. 4 to 20 mA loop powered with HART [optional 4-wire Modbus
RTU (in preparation)], providing accurate level measurement to ranges of 30 m (98.4 ft). Its long range, narrow beam make LR120 suitable for wet wells with obstructions or solids level measurement, for example aggregates or plastic pellets. Programming is convenient using the Bluetooth connection and SITRANS mobile IQ application on your smart device.
