Siemens 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
