AMETEK Land introduced two short-wavelength radiometric infrared borescope imaging cameras — NIR-B-2K and NIR-B-640 — for a wide range of continuous industrial furnace process monitoring and control applications requiring highly accurate temperature measurement.
The NIR-B-2K provides a thermal image with outstanding definition of nearly 3 million pixels (1968 x 1472), 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 optimize furnace temperature. This helps to save energy, increase efficiency, and reduce emissions.
Designed specifically to produce high-definition thermal images in a temperature range from 600 to 1,800°C (1,112 to 3,272°F), 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°x71° field of view to ensure an extensive measurement area covering stock, refractories and burner/heating zones in a single thermal image.
The NIR-B-2K uses advanced spectral filtering, unaffected by furnace temperature and gases, to deliver real temperature readings and clear monitoring of the interior. Combined with the advanced thermal imaging monitoring and process software (IMAGEPro), the patented background compensation corrects for background reflection, enabling continuous, correct stock temperature readings.
With continuous coverage via Gigabit Ethernet connection and automated alarm outputs, the NIR-B-2K is recommended for use in rotary furnaces, reformer tube furnaces, coal-fired power boilers, glass melt furnaces, cement kilns, and biomass boilers.
The NIR-B-640 is a short-wavelength, radiometric IR borescope imaging camera for continuous temperature measurement in furnace applications with a higher differential temperature in the field of view. Measuring in a 600-2,000°C (1,112-3,632°F) range, the NIR-B-640 provides a high-resolution thermal image with real-time, continuous, high-accuracy temperature readings. It uses wide dynamic range imaging technology for temperature-reading accuracy over the entire wide temperature range, for accurate, continuous temperature profiling of the furnace and stock.
The NIR-B-640 can accurately measure “cold” and “hot” areas in one frame or image. This allows the entire process to be monitored without switching to different temperature ranges during operation. The high-resolution image, combined with the wide-angle (90°x67.5°) field of view, allows multiple areas in the lane to be imaged and measured simultaneously. With advanced digital communications, the image and data can be viewed in real-time in a safe area control room.
The NIR-B-640 is recommended for reheat furnaces, continuous casting (zone 1), heat treatment, and annealing furnaces.
