Highest accuracy ultrasonic level with Profibus PA
The Sitrans Probe LU, the ultrasonic level transmitter with the highest accuracy on the market, 0.15%, now offers Profile 3 Class B connectivity to a HART or Profibus network
The newly designed Easy Aimer, now a standard feature, makes installation and orientation of the device simpler, and improves the signal on sloped solids surfaces.
It allows proper orientation of the beam without removing the device from the process.
In addition, the antenna system has been re-designed for lower loss and improved gain, thus increasing the signal to noise ratio.
The Sitrans LR 400 4-wire power and 24 GHz frequency-modulated, continuous wave (FMCW) radar technology ensures superior performance for long-range measurement up to 50m (164 ft), even through extreme dust or in applications with low dielectric liquids such as solvents, petrochemicals, oils or LPG (liquefied petroleum gas).
Advanced echo processing means the Sitrans LR 400 is unaffected by obstructions and automatically responds to changing vessel conditions.
The result is repeatable, fast, and reliable measurement.
The Sitrans LR 400 features a rugged, industrial, aluminium enclosure and robust screw terminals with ample room for wiring.
Operating in extreme conditions, Sitrans LR 400 offers a 200C (392F) temperature rating as standard with an option to 250C (482F).
