SIEMENS SITRANS LR120 Radar Level Transmitter

BENEFITS

Powered by a 4 to 20 mA loop with optional HART [or 4-wire Modbus RTU], this transmitter offers accurate level measurements with a range of up to 30 meters (98.4 feet). Its long-range capabilities and narrow beam design make the LR120 ideal for wet wells with obstructions or solids level measurement, such as aggregates or plastic pellets. Plus, programming is effortless with Bluetooth connectivity, allowing seamless setup via the SITRANS mobile IQ application on your smart device.

  • 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.
