ATEX is the short form of the French expression "ATmospheres EXplosibles“, referring to (potentially) explosive atmospheres.
The continued trend to automatisation and data collection in many areas of industry and daily life has led to an increased number of primary batteries used in potentially explosive atmospheres in recent years. ATEX Directive 2014/34/EU regulation applies to all equipment intended for use in explosive atmospheres, whether electrical or mechanical, including protective systems. Which means that any IoT monitoring or telemetry system such as tank monitoring systems, valve sensors, level sensors, gas detectors, temperature sensors, etc. and all their components —including batteries— have to be IECEx certified or compliant if they are to be installed or used in hazardous locations.
