You need a digital camera that’s tough, because that’s the world you work in. You need a digital camera that will shake off the trials of working in a hazardous location and still keep functioning. You need a digital camera that is certified to be safe to use. You need a digital camera that is Tough, Reliable and Certified, you need TOUGHPIX II TRIDENT EDITION explosion proof compact digital SLR. (more…)
You need troubleshooting tools that are rugged, reliable, efficient and accurate. Tools that can help you detect problems fast and communicate them easily to your team. That’s what the CorDEX TC SERIES Intrinsically safe cameras do. They give you the ability to see heat and detect problems before they happen. All from a tool that is virtually indestructible in everyday use. (more…)
CorDEX has added Extech Safety Systems as an authorised distributor in Sub Saharan Africa.
The ToughPIX II TRIDENT EDITION Explosion Proof Digital Camera is designed and certified with the professional inspector in mind. ATEX, IECEx and locally IA certified Ex d IIB+H2 T6 Gb / II2G Gb T6, for use in hazardous areas ensures it can go safely where most cameras and phones cannot. With its high intensity on board strobe flash, ToughPIX II TRIDENT EDITION lights up the darkest areas making high quality digital imagery easier and clearer than ever. Coupled with 5x optical zoom, 4x digital zoom, anti-shake technology and additional close-up macro lenses, ToughPIX II TRIDENT EDITION gives you the flexibility you need to do your job, any job and get the results you need.

Atlanta, Ga. (June 1, 2016) – Aegex Technologies LLC has added Extech Safety Systems as a Reseller in South Africa of its intrinsically safe Windows 10 tablets that bring real-time communications to the world’s most hazardous industrial operations.
For almost 30 years, Johannesburg, South Africa-based Extech, has been providing required instrumentation, especially intrinsic safety, for hazardous area operations in Southern Africa. (more…)
The Society for Automation, Instrumentation, Measurement and Control (SAIMC) president Vinesh Maharaj recently inducted Gary Friend as a Fellow of the Institute for his work on SABS technical committees reviewing international IEC specifications to be adopted as South African standards. SABS TC65 was in existence due to the activities of SAFA (South African Flameproof Association) but there was no local mirror for IEC TC65 (industrial process-measurement, control and automation). Working with SABS and representatives of companies like Sasol and Proconics, SABS TC165 was established in September 2014. Hans van de Groenendaal spoke to Friend on these standards.
For an explosion, all three of gas/dust, oxygen and source of ignition (spark or heat) need to be present. Intrinsic Safety works on the principle of removing the source of ignition. This can be achieved by using a Zener Barrier or Galvanic Isolator.
The protection of electrical apparatus for use in flammable atmospheres is embracing a new technique: Ex ic. As a logical extension of the existing intrinsic safety concept, it formalises the application of intrinsic safety in Zone 2 hazardous areas, but users and manufacturers alike are wrestling with the details. The discussion centres as much on the withdrawal of the Ex nL technique, as on the application of Ex ic which replaces it. The paper deals primarily with the impact on countries that follow IEC and ATEX practice, but there are parallels with the ‘non- incendive’ technique that is adopted in North America.
As wireless devices such as mobile phones and laptop computers become more reliable and cost effective, there is growing interest amongst the process industry as to the benefits to be found from enabling such devices to be used in hazardous areas. However, unlike most industries this is not a simple task. Installing wireless networks in hazardous areas requires careful, expert planning and execucution. John Hartley, Managing Director of Extronics, explains the hazards posed by radio frequency sources and the issues involved when installing wireless networks in hazardous areas, and how to minimise the potential risk.
