ترانسميتر راداری |
|
|
|
در بسياري از محيط هاي صنعتي جهت اندازه گيري سطح مخازن و يا به عبارت ديگر سطح مايع از سنسورهاي راداري استفاده مي شود. در اين سنسورها از ارسال امواج به سطح مايع و بازتاب آن جهت اندازه گيري سطح مايعات استفاده مي شود.اين سنسورها معمولاٌ مجهزبه يك نمايشگرجهت نمايش سطح مخزن به صورت درصد و يا متر مي باشد.
كاربرد : مناسب مايعات كف آلود ومواد پودري

Features and Benefits
--26GHz radar level meter
--Non-contacting, no abrasion and contamination
--Small-sized antenna for easy installation, horn mouth size 46mm, 76mm, 96mm and 121mm optional
--Shorter wave length, better reflection achieved on inclined solid surface
--Smaller dead zone 0.2-0.5m, better results ensured even in cannikin measurement
--Small beam angle and concentrated energy to avoid interferences
--Hardly influenced by corrosion with PTFE lining
--Hardly influenced by changes of steam vapor, temperature and pressure
--Hardly impacted by heavy dust with blowing unit
--High SNR to ensure performance even under fluctuation
--Choice for solid media and media with low dielectric constant
--short radar wave, no harm to human or environment
