Explosion-proof Structure
The enclosure design of the Camera guarantees that no external explosion, caused by internal
operation when explosive gas mixture gets inside, can happen. Several factors have been
considered to guarantee the explosion-proof performance, such as enclosure intensity, junction
surface gap and length among components, and maximum surface temperature of the
enclosure.
After the welding and finish machining, the enclosure can sustain the severe hydrostatic test.
With 10 s –20 s 2 Mpa test pressure , there is no water dripping and deformation.
When the Camera is working normally, the maximum surface temperature of the enclosure is no
more than:
80°C; under the environment with T6 explosive gas and ambient temperature: –40°C to
+55°C;
100°C; under the environment with T5 explosive gas and ambient temperature: -40°C to
+60°C;
The observation window is made of tempered glass, and it has passed impulse test and thermal
shock test.
(IP) degree of protection of enclosure: IP68 (1 m/1 h).
The Camera adopts gland packings to lead the cable in, which makes the cable fully
compressed without loosen.
