Intrinsic Safety

Buying an Ex digital camera often costs many times that of its non-Ex equivalent. CorDEX has published a checklist to help potential users work their way through the maze of features. Ranging from affordable point-and-shoot models to high end compact digital SLRs, intrinsically safe refers to a method of protection that prevents ignition by spark of thermal means.

The calibration of analogue signals from myriad sensors and transducers in a process plant is essential not only to ensure correct readings on instruments but also for the feedback signals required for stable process plant operation. Continue reading →

Please note this blog was originally published on the 11th August 2014. It was updated on the 8th September 2021 to include new information about gas detecting thermal imaging cameras, as well as relevant gas detector, flue gas analyser, and thermal camera models. Detecting gas has come a long way since the Victorian days when miners would use a canary as an early warning indicator of toxic gases such as carbon monoxide, methane, or carbon dioxide.
