Thermal imagers for industrial furnaces

Ametek Land has introduced two short-wavelength radiometric infrared borescope imaging cameras, NIR-B-2K and NIR-B-640, for a range of continuous industrial furnace process monitoring and control applications requiring highly accurate temperature measurement.

The NIR-B-2K, which provides a thermal image with a definition of nearly 3 million pixels (1968 x 1472), is unaffected by the hot atmosphere and gases of the furnace, and allows operators to measure from any of three full radiometric-calibrated megapixels, providing data to optimise furnace temperature. This capability helps to save energy, increase efficiency and reduce emissions.
Designed specifically to produce high-definition thermal images in a temperature range from 600 to 1800°C, the NIR-B-2K delivers continuous process monitoring and control for large furnaces. Needing only a narrow opening in the furnace wall, the wide-angle lens provides a 95° x 71° field of view to ensure an extensive measurement area covering stock, refractories and burner/heating zones in a single thermal image.
The second release is the NIR-B-640, a short wavelength radiometric infrared borescope imaging camera for continuous temperature measurement in furnace applications with a higher differential temperature in the field of view.
Measuring in a range from 600 to 2000°C, the NIR-B-640 provides a high-resolution thermal image with real-time, continuous, high-accuracy temperature readings. The device utilises the latest wide dynamic range imaging technology, providing the highest available temperature reading accuracy over the entire temperature range, for accurate, continuous temperature profiling of the furnace and stock, says Ametek Land.
Ametek Land’s NIR-B-640 can accurately measure ‘cold’ and ‘hot’ areas in one frame or image. This functionality allows the entire process to be monitored without switching to different temperature ranges during operation.
