Are your devices certified for use in hazardous areas? Practically every wireless device manufacturer serving harsh industrial environments has been asked that question before. It is being posed more frequently than ever thanks to the IoT revolution. Process industries are increasingly adopting strategies for improved digitization across their sites and facilities. This naturally leads to questions about safety certification. If you are one of the few manufacturers who hasn’t been asked about safety-certified wireless devices already, don’t worry, it is only a matter of time. A common misconception among buyers is that standard wireless devices can be easily certified retrospectively. This is rarely the case.

Flame Path Flame paths are gaps within the enclosure that, if an internal explosion occurs, ensure that by the time the flame has reached the end of the flame path it has […]
