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.
Building on more than twenty years of thermal imaging experience, AMETEK Land has continued to widen its range of temperature measurement solutions by launching the NIR Borescope Glass. With the NIR-B Glass it is possible to use the proven technology of the NIR Thermal Imager to accurately and continuously profile the temperature of the entire furnace, including glass, refractory walls and port arches and the crown/roof, with only a small opening in the wall. Thermal imaging inside refractory lined furnaces, boilers and glass melt tanks normally requires the plant operator to cut large openings in the refractory to enable viewing of the critical area. This can cause significant wasted energy from heat loss and can be difficult to keep the opening free from debris. The NIR-B Glass only requires a small diameter hole through the furnace casing and refractory to accommodate the 90 degree field of view wide angle lens tip.
The NIR Borescope Glass offers significant advantages over the traditional methods of furnace monitoring. The NIR-B Glass offers continuous, labour free monitoring whereas manual visual inspection can take hours to complete, is not continuous and unreliable due to user error. A visual camera does not provide a temperature reading, with the NIR-B Glass you can see the process and measure the temperature at any point within the 324,000 pixel image and set alarms to detect air and glass leaks affecting the temperature and efficiency of the furnace. Also, Areas of Interest (AOI) can be user defined and trended, showing max, min and average temperatures and by using the included DVR function you can replay events and stop at any frame to measure multiple temperatures at the same point in time, particularly useful if you are measuring port arch temperatures at the moment of reversal.
Optional Auto-Retract System provides a further level of protection from damage by overheating, should the water or air services fail.
