SITRANS LR100 Series

For level measurement of liquids or solids. Featuring Bluetooth wireless technology for hassle-free level measurement. Featuring 80 GHz and range up to 30 m (98 ft).

For short distances with cable: basic 4-20 mA measurement to 8 m with cable

The first choice: with communications, hazardous approvals options, and range to 15m

For flooding conditions: with communications, longest range to 30 m, and optional submergence shield for flooding protection

For short distances: basic measurements to 8 m with terminal connection

When you need a display: with HART communication, hazardous approvals, local HMI option, and range to 15 m

Key Features

  • 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

 

Supplementary Components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions. Please find more information here.

The SITRANS LR100 Advantage

Hassle-free

SITRANS mobile IQ app uses Bluetooth wireless technology eliminating the need of special commissioning tools. Compact size and narrow beam makes installation easy for level measurement of liquids, slurries or solids.

Performance when you need it

Signal-killer conditions like condensation, buildup or solids are no match for the extreme sensitivity of this transmitter with its custom-designed radar chip. The weakest signals are still detected.

Maximise inventory assets

Zero blanking distance means the measurement range is right up to the sensor. Combined with an accuracy of 2mm ensures confidence in inventory levels for your operation success.

Optimise process for better business

Ready for Digitalisation and with HART 7.0 or optional Modbus RTU. Integrate intelligent, value-adding data locally or to the cloud.

Trust the proven

Over 170 years of Siemens innovative engineering experience and millions of installed instruments in the field.
