Threaded PVDF Antenna Opens Up New Applications for Siemens Radar Level Transmitter
ATLANTA, December 8, 2011 – Siemens’ Industry Automation Division has launched the Sitrans LR250 radar level transmitter with a new 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.
Sitrans LR250 threaded PVDF antenna is designed for extreme conditions characteristic of acids, alkalis, and other corrosive chemicals: some examples include sodium hypochlorite, sodium hydroxide, and sulfuric and hydrochloric acid applications. These applications are not suitable for stainless steel and usually require transmitters be made from exotic and costly materials. However, the Sitrans LR250 threaded PVDF antenna is able to withstand such environments while remaining a cost-effective solution. It also uses FDA-compliant materials suitable for use in food and beverage, chemical, and water treatment applications.
The Sitrans LR250 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 Sitrans LR250 is operational in minutes and the infrared handheld programmer supports local programming.
Fully functional diagnostics comply with Namur NE 43 and the Sitrans LR250 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). Key fields of application for the Sitrans LR250 include bulk liquid storage tanks, process vessels with agitators, vaporous liquids and low dielectric media.
