SITRANS LR100 Series Radar Transmitters
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.
-
Description
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
