Product Options


The SITRANS LR 200 is a 2-wire loop-powered radar level sensor designed for liquid storage applications up to 20m.

  • Easy installation
  • HART comms
  • 5,8 GHz pulse radar technology
  • High signal-to-noise ratio

SITRANS LR 200 is a cost-effective radar level measurement solution for liquid bulk storage or simple process vessels. The 2-wire loop-powered pulse radar instrument is ideally suited for chemical plants and tank farms.

The Siemens SITRANS LR 200's unique design allows safe and simple programming using the Intrinsically Safe handheld programmer without having to open the instrument's lid. It also features a built-in alpha-numeric display in four languages. The SITRANS LR 200 radar level sensor has a standard Uni-Construction polypropylene rod antenna that offers excellent chemical resistance and is hermetically sealed. With other instruments, you may need to consider compatibility of multiple materials including the seal between the materials. The Uni-Construction antenna features an internal, integrated shield that eliminates vessel nozzle interference.

Start-up is easy with as few as two parameters for basic operation. Installation is simplified as the electronics are mounted on a rotating head that swivels, allowing the instrument to line up with conduit or wiring connections or simply to adjust the position for easy viewing.

The Siemens SITRANS LR200 radar level sensor features patented Sonic Intelligence signal-processing technology for superior reliability.

  • Uni-Construction polypropylene rod antenna standard
  • Easy installation and simple startup
  • Programming using infrared intrinsically safe handheld programmer, SIMATIC PDM, or HART
  • Patented Sonic Intelligence signal processing
  • Auto False-Echo Suppression of fixed obstructions
  • Various flanges, horn and waveguide antenna options available
