Description

• SITRANS LR250 with threaded PVDF antenna is a 2-wire, 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage and process vessels including corrosives or aggresive materials, to a range of 10 m (32.8 ft).
• SITRANS LR250 includes a graphical local user interface (LUI) that improves setup and operation by including an intuitive 
• Quick Start Wizard, and echo profile displays for diagnostic support. Startup is easy using the Quick Start wizard with a few parameters required for basic operation.
• The 25 GHz frequency creates a narrow, focused beam allowing for smaller antenna options and decreasing sensitivity to obstructions.
• SITRANS LR250’s unique design allows safe and simple programming using the Intrinsically Safe handheld programmer without having to open the instrument’s lid.
• SITRANS LR250 measures superbly in small vessels and in tanks/vessels up to 10 m (32 ft) on materials with dk > 3.

Key Applications: liquid bulk storage tanks, process vessels with agitators, vaporous liquids, temperatures to +80 °C (+176 °F), corrosive and aggressive materials, media with dielectric (dk) ≥ 3 (application dependent) and applications requiring functional safety

Benefits

• Fully insulated PVDF antenna design for use in chemical and sanitary environments where aggressive and corrosive materials are used  
• Cost effective replacement for transmitters made of exotic materials  
• Graphical local user interface (LUI)makes operation simple with plug-and-play setup using the intuitive Quick Start Wizard  
• LUI displays echo profiles for diagnostic support  
• 25 GHz high frequency and 2" (50 mm) process connection/antenna allow for easy mounting in nozzles  
• Insensitive to mounting location and obstructions, and less sensitive to nozzle interference  
• Short blanking distance for improved minimum measuring range to 50 mm (2") from the end of the antenna
• Communication using HART® or PROFIBUS PA, or FOUNDATION Fieldbus  
• Process Intelligence signal processing for improved measurement reliability and Auto False-Echo Suppression of fixed obstructions  
• Programming using infrared Intrinsically Safe handheld programmer or over a network using SIMATIC PDM, Emerson AMS, or Field Device Tools, such as PACTware or Fieldcare via SITRANS DTM  
• Suitable for use in Safety Related Systems in accordance with IEC 61508/61511 (SIL-2)
• 3mm (0.118 inch) accuracy in accordance with IEC 60770-1
