Reliable dry bulk solids level measurement helps avoid accidental overfill or material outages that can reduce plant productivity. Siemens SITRANS LR400 is a four-wire, 24 GHz FMCW radar level transmitter for continuous monitoring of liquids and slurries in storage and process vessels including high temperature and high pressure, to a maximum range of 164 feet. For safe on-site local programming, without opening the LR400's case, use the Intrinsically Safe handheld programmer. Or, you can use SIMATIC PDM for easy remote programming.

The SITRANS LR400 operates virtually maintenance free, eliminating the ongoing costs associated with traditional level measurement technologies. By avoiding unnecessary shutdowns, eliminating manual readings, reducing instrument maintenance, and making level data accessible in your control room, the LR400 can provide a rapid return on investment, improve working conditions in your plant, and let your skilled staff move on to more productive activities.
