Siemens SITRANS LR250 two-wire continuous radar level transmitter for liquid and slurry applications is easy to install and quick to configure. Its narrow horn and beam, along with Siemens Process Intelligence algorithms, ensure that the LR250 provides high accuracy of low and high levels, even with low dielectric media.

The LR250 is now available in four versions: a horn antenna for liquid and slurry measurement, a PVDF antenna for use with corrosive or aggressive materials, a flanged encapsulated antenna for use with corrosive or agressive media, and a hygienic encapsulated antenna for sanitary applications.

The LR250 horn antenna model is a suitable replacement for the retired SITRANS LR400 liquid level radar transmitter.

• 25GHz pulse radar for continuous level measurement of liquids and slurries
• LR250 Horn Antenna: 66-foot range, process temperatures -40° to 392°F, pressures to 560 PSIG
• LR250 PVDF Antenna: 33-foot range, process temperatures -40° to 176°F, pressures to 72.5 PSIG
• LR250 Flanged Encapsulated Antenna: 66-foot range, process temperatures
  -40° to 338°F
• LR250 Hygienic Encapsulated Antenna (Sanitary): Minimum 2" to 66-foot range — use more tank for your process, process temperatures -40° to 338°F
• Non-contact: Not influenced by dust or acoustic noise (filling)
• Narrow beam angle allows installation almost anywhere in your tank
• Process Intelligence algorithms for echo processing adjust on the fly to changes in process conditions
• Use with Siemens infrared handheld programmer for local configuration; Compatible with SIMATIC PDM via HART for configuration with a PC
