The series consists of five transmitters:

  • SITRANS LR100 - for basic measurement to 8 m
  • SITRANS LR110 - with communication and hazardous approvals options and range to 15 m
  • SITRANS LR120 - with communication, longest range to 30 m and optional submergence shield for flooding protection.
  • SITRANS LR140 - for basic measurements to 8 m with terminal connection
  • SITRANS LR150 - with HART communication, hazardous approvals, local HMI option, and range to 15 m

Benefits

  • Easy Bluetooth® wireless technology for easy and quick setup with Siemens SITRANS mobile IQ app
  • 80 GHz narrow beam and small size allows for the easiest installation and commissioning
  • Custom radar microchip means signal killer conditions like condensation, buildup or fluffy solids are no match for the extreme sensitivity of the microchip, the weakest signals are still detected
  • Zero blanking zone allows measurement range right up to the sensor and with an accuracy of 2 mm you can get rid of costly manual measurement methods
  • Digitalization and Industry 4.0 ready with HART 7.0 or optional Modbus RTU for intelligent, value adding data locally or to the cloud
