SIEMENS Brand New SITRANS LR250 Process Instrumentation
Level Measurement Continuous very competitive price
SITRANS LR250 is your first choice for liquid level measurement in storage and process vessels up to 20 meters (66 ft).
With its range of antennas, this transmitter can handle whatever you need it to. Its new flanged and hygienic encapsulated antennas mean
corrosive or aggressive materials and hygienic or sanitary requirements are no challenge for this transmitter.
SITRANS LR250 is a 2-wire, 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage
and process vessels including high temperature and pressure, to a range of 20 m (66 ft).
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 allows for small antennas 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 inch) from the end of the antenna
Communication using HART, 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
Functional Safety (SIL 2). Device suitable for use in accordance with IEC 61508 and IEC 61511
3 mm (0.118 inch) accuracy in accordance with IEC 60770-1
Suitable for API 2350
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 horn antenna options and decreasing sensitivity to obstructions.
SITRANS LR250’s unique design allows safe and simple programming using the Intrinsically Safe handheld
programmer without saving to open the instrument’s lid.SITRANS LR250 measures superbly on low dielectric media,
and in small vessels, as well as tall and narrow vessels.
* Key Applications: liquid bulk storage tanks, process vessels, vaporous liquids, high temperatures,
low dielectric media and applications with functional safety requirements
