CD ATEX

Intended use

Membrane level indicator to be used to control normally the medium or minimum level of bulk solids in silos or vessels. The models are certificated for use in potentially explosive Dust and Gas atmospheres as well as in hybride mixtures (Dust + Gas) hazardous areas.

These controllers consist of a switch actuated by a membrane and it is recommended for dusty and powdery, granulated and grainy bulk goods like dust, flour, grain, sand, plastic, etc. with an easy flow and a bulk density from 0.3 to 2.5 t/m3.
