explosion proof cameras
EXPLOSION PROOF CAMERAS ELBEX
They are ideal for using in Coal Mines, Oil Refineries Oil Fields,
Chemical Factories …
ELBEX cameras are base on EEX Standard and they are capable
to use in Class II & I. In other words inHazardous areas
which an explosive atmosphere consisting of a Mixture with
air of flammable Substances In the form of gas, vapor or
mist is likely to occur in normal operation occasionally.
Moreover, they can Use in Coal Mines and underground
applications, which the Firedamp gas such as Methane is
exist.
Standards:
1. Protection method of these cameras, in hazardous area,
is base on EN50014 & EN50018 standards.
2. Type of Protection essentially is (de) Increased Safety
and Flameproof Enclosures.
3. Ingress Protection Rating is (IP66) which totally protected
against dust and against heavy seas.
Flame proof Enclosure:
Most popular kind of protection is Flameproof Enclosure.
This standard equipment is A very sturdy Case specifically
designed for use in explosive atmospheres. The potentially
incentive components are Contained within an enclosure into
which the flammable atmosphere can enter but which will
contain any Resultant explosion and prevent it's transmission
outside the enclosure.There are two main methods of Protection
for The enclosures to contain the explosion and energy limiting
methods that ensure that if a Spark generate There is not enough
energy in the spark to ignite the atmosphere. Main character
(The "d” type Enclosure) is preventing an internal inflammation
from igniting the ambient atmosphere and Keeps the Outside
temperature of the enclosure below the ignition temperature of
the ambient gas vapors On the other hand, dusts, if it will avoid an
external explosion, it can be approved
(Acceptable to the Authority having jurisdiction).
Classification of Explosive Gases:
The most dangerous explosion is in IIC group, IIC being the most volatile and
the most easily ignited.
Temperature Classification:
Temperature class or ignition temperature of the gas or vapor involved
according to the table below:
T-Class Hazards which will not ignite at temperatures below:
T1 450°C
T2 300°C
T3 200°C
T4 135°C
T5 100°C
T6 85°C
