Siemens Radar level Transmitter SITRANS LR100 Series
SITRANS LR100 series
SITRANS LR100 series are 80 GHz compact radar transmitters with Bluetooth wireless technology. For level measurement of liquids or solids. Featuring a narrow beam for flexible installations in existing vessel openings – or non-intrusively through plastic vessels.
The series consists of five transmitters:
- SITRANS LR100 – basic 4-20 mA measurement to 8 m with cable
- SITRANS LR110 – with communications, hazardous approvals options, and range to 15 m
- SITRANS LR120 – with communications, longest range to 30 m, and optional submergence shield for flooding protection
- SITRANS LR140 – 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
