Installations, in which explosive gases or dust mixtures can occasionally appear, must be assessed and divided into zones according to the 1999/92/EC ATEX Directive. The resultant explosionprotection document represents the basis for determining what explosionprotected components are needed. Such installation components are planned and manufactured according to ATEX 2014/34/EU.
The suitability of such components for corresponding zones must be verified by means of sample testing. The quality of the equipment is ensured by means of an audited Quality Management System as well as annual ATEX-specific internal and external audits.
For explosion-relevant areas, FEMA has a number of pressure switches and thermostats featuring ignition protection by means of flameproof enclosure. For the Ex-i area, various different pressure switch product lines equipped with gold contact and Ex-i are available under the heading “Simple Electrical Apparatus.”
