Sight glass USL53-LED with hinged bracket
Applications
  • Applications in the chemicals, pharmaceutical,
    biogas and food processing industries:
    For illuminating the interior of vessels, tanks,
    agitators, silos and other generally closed
    containers and reactors and also in visual
    flow indicators in non-explosive environments.
  • ESL53-LED-KS:
    for general use with hinged bracket
  • ESL53-LED-B:
    special sterile version for flange attachment
    for fitting over flanges, collars, etc.
  • For mounting on sight glass fittings:
    This sight glass luminaire is designed for
    universal applications and is ideal either in
    combined sight and light ports (single-flange version)
    or with separate ports (two-flange version).
Operating conditions
  • Independent of vacuum/pressure in the vessel.
    Under no circumstances should a sight glass luminaire
    be used as a substitute for the cover flange or instead
    of the complete sight glass flange assembly, or on its
    own to close a vessel port.
Operating temperature
  • Maximum admissible ambient temperature: 40°C
   
Materials
  • Luminaire body: stainless steel 1.4404
  • Hinged bracket and flange adapter for fastening the luminaire
    to screw-type sight glass fitting DN 50/65: stainless steel 1.4301
  • Connecting cable: 3 m (3 x 0.75 mm²) factory-fitted
    (other lengths on request)
Advantages
  • Compact design, powerful light output:
    Glare-free illumination; fits circular sight glass fittings to
    DIN 28120/DIN 28121 or similar, screw-type sight glass fittings
    in compliance with DIN 11851, as well as METAGLAS® and
    BioControl fittings.
Straightforward installation using a special attachment, ensuring convenience of use:
  • The luminaire is fixed to the cover flange by a hinged bracket
    in the case of circular sight glass fittings and visual flow
    indicators. With screw-type sight glass fittings, the luminaire
