Head-Mounted Wearable Computer Is First To Get ATEX Certified

RealWear unveils what it calls the world’s first commercially available intrinsically safe wearable computer (ATEX Zone 1 and Class 1 Division 1). The company claims its HMT-1Z1 is the only head-worn computer that presents no ignition risk where potentially explosive atmospheres exist during routine operation. Andy Lowery, Co-founder and CEO of RealWear says, “With the launch of the HMT-1Z1, now all workers, even those in potentially explosive areas requiring intrinsically safe equipment, can take full advantage of the freedom and efficiencies available through purpose-built wearable computing.”

 

Intrinsic safety (IS) is a design and protection technique for safe operation of electrical and electronic equipment in hazardous locations by limiting the electrical or thermal energy to limits that cannot cause ignition of explosive gases, even under a fault condition in the device. Zone 1 hazardous areas include petrochemical plants, but also include pharmaceutical, food (grain silos and sugar processing) and cosmetic manufacturing, all of which involve processing potentially explosive substances.  Use cases for these devices include remote mentoring via video collaboration, hands-free document navigation, guided workflow and IoT visualization from process control systems.
