FAQ
Q1: Can we use ordinary instruments in hazardous areas?
A1: No! Ordinary instruments, during normal operation or in the event of a fault, can generate electrical sparks or high surface temperatures sufficient to ignite surrounding flammable gases or dusts.
Q2: Is it mandatory to have explosion-proof certification (e.g., ATEX, IECEx)?
A2: Yes, it is typically mandatory. Equipment must possess corresponding regional certifications for sale and installation in different markets.
Q3: What are the key considerations for the daily maintenance of explosion-proof ammeters/voltmeters?
A3: Maintenance includes:
- Periodic Inspection: Check for mechanical damage, corrosion, or rust.
- Integrity of Fasteners: Regularly verify all fasteners (cover bolts, cable glands) are tightened.
- Cleaning: Use a damp cloth and non-corrosive cleaner to prevent dust accumulation; never clean with power on or cover open.
- Record Keeping: Maintain records of all maintenance and inspection activities.
Q4: Can we open explosion-proof instruments for repair or calibration ourselves?
A4: It is absolutely not recommended. Opening an explosion-proof enclosure must only be performed by specially trained personnel in a safe area. Unauthorized opening voids certification and introduces significant safety risks.
