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.
