Extending the campaign life of a furnace — that is, the period between required interior and refractory refurbishments — depends upon a consistent temperature and thermal profile. 

ImageIR 5300 has a thermal sensitivity of 0.015 K. This signal‐to‐noise ratio is accompanied by integration times of less than 10 µs for technically relevant object temperatures, so frame rates of up to 105 kHz can be realized.

Fotric 326 has a large aperture f1.0 infrared lens for taking radiometric thermal images. A -4 to 1202°F (-20 to 650°C) measurement range cover many applications, including inspecting high temperature objects.

Fluke TiS60+ offers 320 x 240 resolution. Infrared images taken with the fixed-focus thermal image camera capture smaller temperature differences from farther away, according to the manufacturer.

Reheat furnaces are responsible for bringing cold metal to the correct temperature for hot-forming applications such as rolling, extruding or forging. To optimize quality and reduce wastage, the temperature needs to be consistent throughout the product, which requires accurate temperature monitoring. 

A visible thermal imaging system provides high quality lime kiln process monitoring for pulp mills. Combining the camera temperature information with process controls can improve combustion optimization and reburned lime quality and reduce emissions. The system, manufactured by Valmet, also allows visual evaluation of flame shape, size and temperature profile.

Powered by the company’s Lepton thermal microcamera core, Model Flir One Pro LT includes an image enhancement feature that combines the thermal and a high definition visible camera image to produce crisp, detailed images that are easy to interpret. 

Industrial inspection, troubleshooting and diagnostic tool can be used for electrical and electromechanical applications as well as heating. 

Powered by the company’s Lepton microcamera thermal core, the DM166 and DM285 digital multimeters and the CM275 clampmeter have built-in screens to show heat caused by electrical faults.
