SITRANS LR250
Process Instrumentation
Radar Level Transmitter
SITRANS LR250 is your first choice for liquid level measurement in storage and process vessels up to 66 feet (20 m). With its range of antennas, this transmitter can handle whatever you need. Flanged and hygienic encapsulated antennas mean corrosive or aggressive materials and hygienic or sanitary requirements are no challenge for this transmitter.
The all-rounder: Polypropylene lens antenna
- Excels in most industrial applications at a budget-conscious price point
- Lightweight polyester powder-coated horn yields a very high signal
- Highly corrosion-resistance polypropylene and FKM wetted materials for use in a wide range of chemicals with nominal pressure and temperature
- Universal polymeric flanges offer exceptional value and fit DIN, ASME and JIS bolt patterns
The oil and gas specialist: The 316 horn antenna
- Featuring multiple sizes and pressure classes
- PTFE emitter and FKM seal, optional FFKM seal for higher corrosion resistance
- Flanges and threaded process connections to ASME/ANSI and DIN standards, typical in oil and gas applications
- Highest temperature range to
392 °F (200°C) - Ideal for stilling wells and bypass pipes
The Extreme expert: FEA flanged encapsulated antenna with PTFE lens
- Can handle extremely corrosive chemicals and high temperatures/pressures
- Ideal for process control applications in the chemical industry
- Easy to clean FDA-approved TFMTM PTFE lens
- A cost-effective replacement for antennas made of exotic metal
The hygienic hero: HEA hygienic encapsulated antenna
