Guided wave radar level sensor with CSA, ATEX approvals for hazardous locations
July 24, 2006
Monitor Technologies LLC announces the availability of CSA and ATEX certifications for its Flexar™ guided wave radar continuous level measurement product line. The CSA certification includes Class I, Division 1 & 2, Group B, C and D as well as Class II, Division 1 & 2, Groups E, F and G. ATEX certification is Ex II 1/2 GD T75 ... 150C. These approvals allow the benefits of guided wave radar technology to be extended to areas where hazardous and explosive vapors and dust exist. Flexar guided wave radar product is a continuous level measurement device using TDR (time domain reflectometry) principles where radar pulses area focused to the material surface by the unit''s wave guide (typically a heavy duty cable or rod) and the time-of-flight of the pulse reflection back to the instrument electronics is directly related to the empty distance in the vessel and the material level.
