The Sitrans LR560 was specially designed for the continous and contact free level control of bulk solids material in silos. According to Siemens, the 2-wire, 78 GHz FMCW radar level transmitter with its small beam angle of 4° and its very short wavelength allows optimum reflection of the bulk solids material even when confronted with a large material mound and can be used for continuous monitoring of solids in silos up to 100 m. The Sitrans LR560’s “plug and play” performance is suitable for most solids applications, including those with extreme dust and high temperatures to +200°C. The design allows safe and simple programming using the graphic display with control keys on the unit or via an infrared handheld programmer or alternatively via Hard-, Profibus PA and Foundation Fieldbus communication.

The robust stainless steel construction makes the LR560 extremely suitable for all kinds of industrial applications. The unit operates at a high frequency of 78 GHz thus achieving a very small beam angle which eliminates any signal interference at the flange but allows optimum reflection of the bulk solids material. The flange can be adjusted to ensure a perfect positioning of the LR560, ie the angle of the beam can be set to a specific point, for example the outlet of the silo. The lens antenna is highly resistant to material deposits and offers a self-clean function for extremely sticky solids using an air flush connection. The Local display interface (LDI) allows programming and diagnostics on-site.
