EXH Series Description
The EXH housings are made with strong Anticorodal aluminium die-cast alloy of
AISi Mg EN AB- 42000 group.
All external components are stove enameled using powder offering an excellent
resistance to UV rays, salt-spray, environment polluting substances.
Ex-proof housing with the same specifications as the EXHC series but fitted with
a patented device for the protection of the glass which gives clear vision in
dirty environments.
The glass protection device consists of a connection flange with the housing, a
closing flange and an explosion-proof central body containing a rugged and
transparent glass, a motor powered in 24Vac, two windings and a transparent
Mylar film, installed just in front of the glass. The motor drives, through four
pinions with gear rim, the winding for recovering the dirty Mylar film, while at
the same time the other winding installed on the opposite side releases the
clean film. NOTE: the control unit of the glass protection device is not
supplied with the product. The transparent Mylar film, 80mm wide and 18m long,
allows 350 steps. When the film is dirty, the operator will activate the motor
shifting the film to obtain a clean camera picture (the step for allowing the
complete shift of the dirty film is about 50mm). The end of the Mylar film will
be indicated to the operator through marks printed on the last 50cm of the film.
