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.
Testing for gasses has come a long way since the days when Victorian miners would take a canary down a mineshaft as an early warning indicator of toxic gases such as carbon monoxide, methane or carbon dioxide.
