Importance of Explosion-Proof Methods
Explosion accidents can occur during the storage, transportation, and production of explosive substances. Therefore, electrical equipment used in hazardous areas must employ special and effective preventive measures to avoid becoming ignition sources.
The applicable explosion-proof methods include:
- Flame-proof (Ex d)
- Increased Safety (Ex e)
- Intrinsic Safety (Ex i)
- N Type (Ex n, only in Zone 2)
- Encapsulation (Ex m)
Among these, Intrinsic Safety and Flame-proof are the most widely used, and these two explosion-proof certifications are the primary focus for Jiwei. You can verify the certificates by visiting the official website of the National Explosion-proof Product Quality Supervision and Inspection Center here and entering the certificate number from the table above.
Jiwei consistently prioritizes product quality and production safety and will continue to provide high-quality and reliable level measuring instruments for users worldwide.
