Siemens SITRANS LR250: A cutting-edge 2-wire, 25 GHz pulse radar level transmitter engineered for continuous monitoring of liquids and slurries in storage and process vessels, even under extreme conditions of high temperature and pressure, covering a range of up to 20 meters (66 feet).

Part Number: SIE_LR250_2045

BENEFITS

Featuring a graphical local user interface (LUI), the LR250 enhances setup and operation with an intuitive Quick Start Wizard and echo profile displays for diagnostic support. Startup is simplified with the Quick Start wizard, requiring only a few parameters for basic operation.

With its 25 GHz frequency, the LR250 generates a narrow, focused beam, allowing for smaller horn antenna options and reducing sensitivity to obstructions. Its unique design enables safe and straightforward programming using the Intrinsically Safe handheld programmer without the need to open the instrument’s lid.

The LR250 excels in measuring low dielectric media and performs exceptionally well in small vessels, as well as tall and narrow vessels, ensuring accurate and reliable level monitoring.

Graphical local user interface (LUI) makes operation simple with plug-and-play setup using the intuitive Quick Start Wizard
