Intrinsically Safe Power Supply Design: A Step-by-Step Guide
As the Internet of Things (IoT) becomes of growing importance, so does the need for the many sensors and monitoring devices that will exist in the IoT universe. For example, many of these devices monitor the processing of oil and gas wells and pipelines. By the very nature of the processes, a single stray spark near flammable material in these locations could ignite a fire or explosion. These monitoring devices are in place to mitigate the risk of danger to human life and significant damage to assets.
Special considerations and design practices need to be kept in mind—and specific steps followed—when designing for hazardous locations (HazLoc). One such design strategy to meet these goals is “intrinsically safe design.”
This white paper can help designers gain insight into the intrinsically safe design process by demonstrating some best practices to follow when designing a power supply for a HazLoc environment. It provides a high-level process for engineers to follow — with an eye towards certification.
This white paper covers:
- The road to certification
- Five steps to optimal intrinsically safe power
- Detailed examples describe steps necessary for the design of externally powered, battery-powered, and dual-powered supplies.
