NIR-B Glass

THERMAL IMAGING SOLUTIONS FOR GLASS FURNACE APPLICATIONS

 
The NIR Borescope (NIR-B) Glass is a short wavelength radiometric infrared borescope imaging camera, designed to produce high definition (656 x 494 pixel) thermal images, along with providing accurate temperature measurements from any selected points in the image. The camera measures temperatures in the range 1000 to 1800 °C (1832 to 3272 °F) and is suitable for float glass, container glass, borosilicate glass and fibre glass melt furnaces.

Key Features

  1. VIEWING ANGLE - 90° x 67.5° view maximises the area monitored giving a crystal clear and unparalleled internal tank thermal view.
  2. HIGH RESOLUTION 656 X 494 IMAGE - Provide accurate real-time temperature measurements from any selected area of interest or individual points within the 324,064 pixel image.
  3. INTEGRATED AIR PURGE - The unique air purge design maintains a clean lens in harsh process environments. Plus with built-in water cooling, the system minimises air and water flowrate requirements.
  4. PROBE LENGTHS - A 3’ (915mm) borescope is supplied as standard, however other probe lengths available upon request. 
  5. MOUNTING - The retraction system is easily and securely mounted from the furnace steel framework and incorporates a “camera block” cover with integral air purge to provide process sealing when the NIR-B is withdrawn.
  6. THERMOCOUPLE AT NIR-B TIP - Gives the operator an alarm for removing the instrument to prevent damage if maximum temperatures are exceeded
  7. AUTO-RETRACT SYSTEM - Designed to auto-retract and protect the thermal imager from damage by overheating in the event of loss of water flow, air pressure, electricity supply or high borescope tip temperature alarm. The system has an air reservoir (accumulator) to ensure full retraction in the event of loss of air.

SVA PNEUMATIC AUTO-RETRACT SYSTEM instantaneously retracts the instrument from the furnace wall in the event of a failure - air purge, water cooling and mains power, and, if an over-temperature condition detected at the tip.
