Siemens Industry: Antenna for liquid and slurry measurement

Jan. 20, 2012
The Sitrans LR250 radar level transmitter with a new threaded PVDF (polyvinylidene fluoride) antenna for liquid and slurry measurement opens up new applications for this non-contacting level transmitter in extreme conditions such as liquid and slurry.

The antenna is designed for extreme conditions characteristic of acids, alkalis and other corrosive chemicals that do not work well with stainless steel. It uses FDA-compliant materials suitable for use in food and beverage, chemical, and water treatment applications and 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.
