An innovative, mid-wavelength borescope—the MWIR-B-640—enables highly accurate and fully radiometric temperature measurement image data to be taken, stored, and trended over the lifetime of a furnace, providing a continuous and clear view, even through heavy smoke and hot atmospheres.
It is suitable for use in hydrocarbon processing reformers; heat treatment; reheat, cement kiln, and annealing furnaces; biomass, waste, and coal boilers; as well as incinerators. This borescope features advanced spectral filtering and a high thermal and spatial resolution to deliver clear live images of the furnace, boiler, and stock, with more than 300,000 accurate point temperatures measuring in the range of 300 to 1,200°C (572 to 2,192°F) and 500 to 1,800°C (932 to 3,272°F).
The high-resolution image of the MWIR-B-640, combined with a 90-deg. wide-angle field of view, allows multiple areas to be imaged and measured simultaneously. With the wide-angle view into the furnace, image data can be viewed in real-time from the safety of the control room. With only a small opening in the wall, the MWIR-B-640 can accurately profile the temperature of the entire furnace without affecting the furnace atmosphere, the stock temperature, or energy consumption.
Features of the MWIR-B-640 include a high-performance water-cooling system, with low water flow requirements, even in the highest temperature furnaces. The borescope has a thermocouple at its tip, which sounds an alarm when removing the instrument, thus preventing damage if maximum temperatures are exceeded. It also features an integrated air purge to maintain a dust-free optical system while using minimal instrument air. To protect the thermal imager from damage by overheating in the event of loss of water flow, air pressure, electricity supply or a high borescope tip temperature alarm, the MWIR-B-640 is also available with AMETEK Land’s innovative auto retraction system.
