Lenox's NIR-Thermal Imaging Camera System provides temperature measurements from 320,000 individual temperature points

Lenox Instrument Company announces the release of its Furnace Camera HD NIR-Thermal Imaging Camera System, which is designed to provide real-time thermal imaging and near-infrared (NIR) temperature measurement from 320,000 individual temperature points via a Gigabit Ethernet digital connection.

Designed to be installed through a 3.5-inch (89-millimeter) opening in the combustion chamber wall, the camera system’s stainless steel camera housing employs a triple wall laminar flow for water-cooled protection and integrated, low-consumption air-purging to keep the optics clear of debris and enable operation in high-temperature furnace environments up to 4250° F (2345° C). The Lenox NIR Infrared Camera operates at a short wavelength (1µm), which minimizes temperature measurement errors due to variations in target surface emissivity, and is offered with a choice of four models ranging from 1100 to 4250° F (600 to 2345° C).

The Thermal Imaging Thru-Wall System includes Image Processing Software that allows images and data to be viewed, manipulated, recorded and archived. Analytical and process control functions include timed acquisition, multiple point or user-defined areas of interest temperature measurement, multiple temperature line profiles, isotherms, histograms, trending, emissivity adjustment, delta temperature measurement, background correction and choice of color pallets. The software also features automatic storage of images and video on triggered measurement or high/low alarm conditions with optional analog signals or alarm outputs to a PLC or DCS.

Infrared Furnace Camera accessories include an Automatic Retract System that pulls the camera back on loss of water cooling or air, preventing over-temperature damage, and RS485 Input/Output (I/O) modules that can used to integrate the Image Processing Software to process control systems.
