Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 

The encoder type ***78E is a small cylindrical unit (78 mm in diameter, length changes with lid), containing low voltage electronic components.

The type of protection is realized by an Ex-d flameproof enclosure. The three piece construction is manufactured from aluminium, stainless steel or acid-proof stainless steel. The unit comprise four flame-paths, a cylindrical joint between the lid and body, a cylindrical joint between end-cap and body, a threaded cable entry and one cylindrical rotating shaft held in place with 2 precision roller bearings.
