USA - SITRANS LR460 Radar Level Transmitter

Radar Level Transmitter

The SITRANS LR460 is a 4-wire, 24 GHz FMCW radar level transmitter with extremely high signal-to-noise ratio and advanced signal processing for continuous monitoring of solids up to 328 ft (100 m). It is ideal for measurement in harsh conditions and provides excellent results even in extremely dusty environments. The integral Easy Aimer included on the SITRANS LR460 is easily positioned for optimum measurement of solids.

SITRANS LR460 advanced signal processing provides reliable operation on both simple and difficult solids application. SITRANS LR460 features a robust enclosure, flange and horn components. It is virtually unaffected by atmospheric or temperature conditions within the vessel. An optional dust cap is available for sticky solids. Optional air purging is also available for extremely sticky applications. Safe on-site local programming is simple using the Intrinsically Safe handheld programmer. SIMATIC PDM can be used for easy remote programming using HART or PROFIBUS PA. The characteristics of 24 GHz and high signal-to-noise ratio contribute to exceptional signal reflection, regardless of the dielectric value of the medium.


Key applications: long-range dusty applications, cement powder, fly-ash, coal, flour, grain, plastics.


Supplementary Components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions. Please find more information here.
