AMETEK Land releases new borescope to enhance furnace temperature monitoring

AMETEK Land, one of the leading manufacturers of monitors and analysers for industrial infrared non-contact temperature measurement, has launched a new mid-wavelength borescope, the MWIR-B-640, for furnace applications.

The MWIR-B-640 enables highly accurate and fully radiometric temperature measurement image data to be taken, stored, and trended over the lifetime of the 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 new 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 – 1200°C (572 – 2192°F) and 500 – 1800°C (932 – 3272°F).

The high-resolution image of the MWIR-B-640, combined with a 90° 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.

“The MWIR-B-640 is an invaluable tool that will prolong furnace and boiler lifetime, optimise production throughput, reduce energy consumption and improve stock temperatures,” said David Primhak, Director of Development and Product Management for AMETEK Land. “It has a range of innovative features that ensure it is user-friendly, extremely accurate, and offers a high level of asset protection.”

The MWIR-B-640 uses proven thermal imaging technology to accurately and continuously profile the temperature of the furnace and the stock, resulting in improved data accuracy through automation and reduced risk to personnel by minimising the need for an operator to be in the hazardous furnace/boiler area.

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.

Features of the borescope 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.

In addition, it has a range of mounting options to ensure simple installation and is available with a range of probe lengths to suit every application.

It is available with advanced IMAGEPro thermal imaging and data processing software, which supports long-term data trending to enable the early detection of leaks and temperature variations and achieve process optimisation.
