Sight glass luminaire USL05-Ex / USL05-LED-Ex

USL05-Ex / USL05-LED-Ex

Applications

  • For illuminating the interior of tanks, hoppers, silos, agitators
    and other - normally closed - vessels and reactors as well as
    visual flow indicators in potentially explosive environments.

    Gas: Zones 1 and 2,

    Dust: Zones 21 and 22.
  • Suitable for use in food processing industries
  • This Ex-type sight glass luminaire is designed for universal
    applications in potentially explosive environments. It is
    ideal for use in combined sight and light-glass arrangements,
    either as a single flange version or with two separate flanged
    ports.
Operating conditions
  • Independent of the internal pressure / vacuum in vessel.
    Under no circumstances should a sight glass luminaire be
    used on its own to close a vessel port or to replace the
    cover flange or the sight glass / luminaire assembly.
Operating temperature
  • Sight glass luminaires of this series are approved for use in ambient
    temperatures of up to 60°C, depending on the lamp bulb fitted.

Protection
  • IP 65 and IP 67 to DIN EN 60529

Certification

  • EC Type-Examination Certificate BVS 08 ATEX E 133
  • II 2G Ex d IIC T3/T4/T6/120°C Gb
