SITRANS LR500 series are 80 GHz radar level transmitters for continuous monitoring of liquids, slurries, and solids in storage and process vessels.
-
The series consists of four transmitters :
- SITRANS LR510 – threaded lens antenna for liquids
- SITRANS LR530 – flanged encapsulated antenna for extreme conditions
- SITRANS LR550 – polymeric horn antenna for solids and liquids
- SITRANS LR580 – lens antenna with integrated aiming flange for solids
Benefits
