Radar Level Transmitter
SITRANS LR100 series are 80 GHz compact radar transmitters with Bluetooth wireless technology. 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 - for basic measurement to 8 m
SITRANS LR110 - with communication and hazardous approvals options and range to 15 m
SITRANS LR120 - with communication, longest range to 30 m and optional submergence shield for flooding protection.
SITRANS LR140 - for basic measurements to 8 m with terminal connection
SITRANS LR150 - with HART communication, hazardous approvals, local HMI option, and range to 15 m
