Gas Detection Choices and Practices
June 24th, 2009
A recent article published in Health & Safety International reviews the most current gas-detection technologies and their best uses. Some topics covered:
+ In the toxic-gas detection arena, advances in sensor technology have enabled new NTMOS (nanotechnology metal oxide semiconductor) sensors to respond in as quickly as five seconds to deadly hydrogen sulphide gas leaks -– even in extreme temperature and humidity.
+ For combustible gases, the most common detection choices are catalytic and infrared. Catalytics offer lower start-up costs while detecting a wide range of gases and offering good repeatability and accuracy. Infrared detectors are immune to poisoning from contaminants, seldom need recalibrating, and are unaffected by prolonged exposure to high gas concentrations.
+ When implementing a Safety Instrumented System (SIS), project lead times can be cut significantly by choosing products that have undergone third-party SIL certification.
