ATEX Compliance and Electrical Equipment
The DBEX IMN stainless steel sensor is classified as simple 'electrical equipment' and does not require ATEX marking or certification itself. It is suitable for use in intrinsically safe classified zones when connected to appropriate related equipment, such as a Zener barrier or galvanic isolator. The applicable ATEX category and zone depend on the connected safety device.
Applicable Zones: Zone 0, 1, 2, 20, 21, and 22, as defined by standard UNE-EN60079-25 and directive 2014/34/UE.
