IEC 61508 Certification:a standard for all instruments

摘要

Recently,I saw a magazine advertisement;it was a common Ogilvy style with the headline "Safety Is Not An Option." This ad was very eye catching for anyone involved in the design and implementation of safety instrumentation systems.In addition,it described a pressure transmitter that had been certified for safety applications per IEC 61508,SIL 2 and SIL 3.
