so can therefore, be used to take thickness measurements safely where there is a high concentration of dust in the air!
This means….
Zone 21 identifies areas where combustible dust is occasionally present.
Zone 22 identifies areas where combustible dust is not usually present but could be for short periods.
Cygnus 1 Ex has an Intrinsically Safe Design, featuring:
- Limited output energy to prevent ignition of explosive atmospheres.
- Anti-static enclosure to prevent static electricity discharge.
- Multiple redundant safety components.
- In the event of damage or a fault, no high surface temperatures are generated that could ignite an explosive atmosphere.
