HGH Infrared Systems, a provider of thermal imaging systems, has introduced the Pyroscan camera for rotary kiln combustion and entrance cooler temperature monitoring. The pyrometric camera is powered by Ethernet and has a resolution of 1.2 megapixels, allowing accurate measurements of temperatures in every image point, through the 1,300°F to 3,250°F thermal range.

The major innovative feature is the use of high dynamic range (HDR) technology which produces a contrasting image without the effect of underexposed or conversely saturated areas. Additionally, the Pyroscan software provides an anti-dust image processing filter and analyses lines for flame shape monitoring in order to optimise the combustion process. Finally, the new design is completely modular and compact, weighing just 6kgs without the frame. This new camera is contained in a water-cooled housing and a pneumatic actuated frame, which is well-adapted to the harsh environments often associated with industrial kilns.
