Dual-band Infrared Camera Sees Through Flames in Furnaces/Boilers from Mikron

Precision Temperature Measurement, Along With Thermal Images That Are Free of Pixelation

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.

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.
