Summary
- The explosion proof cameras are designed to be safely operated in hazardous areas.
- The main purpose of a special enclosure is to protect the external environment from potential hazards.
- These cameras are internationally certified for explosion protection.
- The certification code indicates the explosion protection level of the camera.
- Therefore, we will explain the certification level with the correct interpretation.
Description
- Certification of Explosion-proof
1. Meaning of prefixes
- Device Category 2 : Category 2 covers 3, but not 1.
2. Certification for Gas
- IIC : Gas subdivisions Level
- Products with an IIC rating can be used in hydrogen and acetylene environments.
- There are 3 kinds of level as IIA, IIB, IIC
- IIA materials have the highest ignition point and are the least hazardous, and IIC materials have the lowest ignition point and are more hazardous.
- So if you get an IIC level, you can use it in IIA and IIB environments.
- Temperature Class T6
- This is a maximum permitted Maximum surface temperature, because higher temperatures can have a greater impact on the environment.
- T6 means that the maximum temperature will remain below 85°C
3. Certification for Dust
- IIIC : Dust subdivisions Level
- This means that it can be used in conductive dust environments.
- IIIB is for non-conductive, and IIIA is for combustible flying.
- So if you get an IIIC level, you can use it in IIIA and IIIB environments.
- Temperature Class T 80°C
- This is a maximum permitted Maximum surface temperature, because higher temperatures can have a greater impact on the environment.
- T6 means that the maximum temperature will remain below 80°C
