SITRANS LR 400

The SITRANS LR 400 is a long-range FMCW radar level transmitter. It is available as a Liquids version for use in liquid bulk storage vessels and as a Solids version with an integral Easy Aimer ball for use on solids applications.

It provides excellent results even during conditions of extreme dust or on low dielectric liquids. The integral Easy Aimer included on all SITRANS LR 400 Solids versions allows for easy positioning for optimum measurement on solids. SITRANS LR 400 is available for standard applications and for applications that require explosion proof protection.

SITRANS LR 400 features robust enclosure, flange and horn components. It is virtually unaffected by atmospheric or temperature conditions within the vessel.

Safe on-site local programming is simple using the intrinsically safe handheld programmer. SIMATIC PDM can be used for easy remote programming.

The characteristics of 24 GHz and high signal-to-noise ratio contribute to exceptional signal reflection, regardless of the dielectric value of the medium. It also features advanced echo processing algorithms for reliable operation on difficult solids applications.

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