Offering 3 selectable temperature ranges including 400 to 1,600°C, dual-band MikroScan 7400 is built around 320 x 240 pixel, 8-14 µm microbolometer that can resolve area smaller than 1/10 sq-in. at 6 ft. IR detector measures passive radiation emitted by target and converts temperature readings into 2D image showing temperature distribution at target surface. It captures 14-bit thermal images with temperature accuracy of ±2% of reading and sensitivity of 0.06°C at 30°C.

Patented, New Dual-Band Infrared Camera Sees Through Flames in Furnaces/Boilers, and Handles Everyday PdM on Electrical Cabinets/Motors
Exclusive mid-wave and long-wave imaging capability doubles applications and halves ROI time; costs thousands less than a cryogenically cooled midwave camera
March 2006 - Patented filtering optics give Mikron Infrared's new MikroScan 7400 thermal camera the unique ability to "see" through furnace flames for boiler-tube monitoring, or to be used for standard predictive maintenance monitoring of electrical cabinets, motors, bearings, etc. The camera offers three selectable temperature ranges, including a high-temperature (400°C - 1600°C) range needed for infrared imaging inside furnaces where combustion temperatures can exceed 1100°C. It also captures simultaneous visual images with on-board voice annotation.
According to Jon Chynoweth, Mikron Infrared marketing director, the company has perfected proprietary technology that allows a low-cost uncooled microbolometer infrared detector to image in very narrow spectral bands at high temperatures. Mikron is now producing the industry's only uncooled, microbolometer, long-wave infrared (8-14 µm) cameras with multi-band imaging capability in the midwave range. The 8-14 µm capability is ideal for typical PdM applications because it is unaffected by sunlight or smoke in a plant, but is normally ineffective with midwave radiation. More important to the user, Chynoweth emphasizes, microbolometer cameras are affordable. "Depending on the resolution of the detector array, commonly 320x240 pixels, microbolometer-based cameras are available in a range of $11,995-$43,000," he explains. "Typical mid-wave cameras that would otherwise be needed for boiler imaging are based on a cryogenically cooled (approximately -200°C) detector. Such cameras are larger, heavier and less portable. They cost $50,000-80,000, consume batteries at a rapid rate, and require service costing up to $15,000 if the cooling system fails."
The MikroScan 7400 is built around a high-resolution (320x240 pixels) microbolometer that offers four times the resolution of standard 160x120 cameras. The superior detector resolves an area smaller than a tenth of a square inch at six feet, resulting in precision temperature measurement, along with thermal images that are free of pixelation. The IR detector measures passive radiation emitted by the target and converts the temperature readings into a two-dimensional image showing the temperature distribution at the target surface. Thermal images can be viewed in grayscale or full color, with several color palettes available to allow best definition and interpretation.
The new camera captures 14-bit thermal images and offers industry-leading temperature accuracy of ±2% (or 2°C) of reading, with sensitivity of 0.06°C at 30°C. In addition to on-board image storage on PCMCIA memory card, the camera can output real-time video in "S" format and NTCS/PAL.
The MikroScan 7400 is battery operated and self-contained in an industrial housing rated at IP54. It includes a special radiation shield and protective window assembly to protect the camera and operator's hands in high-temperature environments. Options include a remote LCD panel and operator controls, and real-time image capture to hard drive via IEEE 1394 (Firewire®) interface with Mikron's MikroSpec R/T software. Additional lenses include wide angle, telephoto, close focus, and the patent-pending SpyGlass(TM) lens that allows imaging of electrical cabinets through the half-inch-diameter, UL-approved Viewport.
