Guided wave radar transmitter certified by exida
Magnetrol Intl. Inc. announced that exida, an accredited global functional safety certification company, has certified the product reliability and the engineering change processes for the Eclipse Model 705 guided wave radar transmitter as Safety Integrity Level (SIL) 3 capable per IEC 61508.
SIL certification is obtained through analysis based on quantitative data and tests indicating the length of time between failures and expected performance in the field. A Failure Mode Effect and Diagnostic Analysis confirmed that the Eclipse Model 705 has demonstrated a solid field use history, includes sound engineering processes, and is designed with capable self-diagnostics.
“The exida certificate gives our customers strong confidence that the Eclipse Model 705 is applicable to safety critical applications,” said Bob Botwinski, Eclipse product manager. "As important, in the past, reliability was measured by MTBF or similar types of calculations.
“Today, reliability is measured by conformance to IEC 61508, and having achieved certification to this standard, the Magnetrol Eclipse Model 705 is recognized at the highest level of reliability based on its performance."
The Model 705 is a two-wire loop-powered level transmitter that operates upon Guided Wave Radar technology, which offers advantages such as high sensitivity and immunity to changing media properties. It can be used in control applications that exhibit visible vapors, foam and surface agitation. Coaxial, Twin and Single rod probes are offered for a wide variety of applications and process conditions up to 6250 psi (430 bar) or +800°F (+430°C).
