The Sitrans LR250 radar level transmitter features a threaded PVDF (polyvinylidene fluoride) antenna for liquid and slurry measurement. The antenna opens up new applications in extreme conditions such as liquid and slurry, for this non-contacting level transmitter. The antenna measures ranges of up to 20 m (66 ft) due to its compact 25 GHz 2-wire transmitter. It is available with Hart, Profibus PA, or Foundation Fieldbus protocols. With the graphical Quick Start Wizard, the unit is operational in minutes and the infrared handheld programmer supports local programming. Fully functional diagnostics comply with Namur NE 43, and the unit has also achieved a SIL 2 functional safety declaration with Safe Failure Fraction (SFF) of 86 percent, making it suitable for use in Safety Instrumented Systems (SIS).
