Explosion-proof versions AM
Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as ignition source. Their constructive measures prevent the occurrence of ignition sparks or hot surfaces.
Certification is performed in close collaboration with national and international certification bodies.
With the AMExC a control with integral local controls is available for the multi-turn actuators SAEx/SAREx 07.2 - 16.2 and the part-turn actuators SQEx/SQREx 05.2 - 14.2.
