| What is the MWIR-b-640 and what is it used for? |
The LAND MWIR-b-640 is a fully radiometric mid-wave infrared borescope imaging camera that looks inside furnaces, boilers and incinerators to measure temperature across the entire scene—over 307,000 accurate measurement points (640 × 480 pixels) in a single image. Unlike visual or near-IR cameras blinded by smoke and combustion gases, the MWIR-b-640's 3.9 µm spectral filtering provides a clear thermal view through heavy smoke and hot furnace atmospheres for continuous furnace profiling, tube monitoring and combustion optimization. |
| What temperature range and resolution does the MWIR-b-640 cover? |
The MWIR-b-640 offers two measurement ranges: 300-1,200°C (572-2,192°F) and 500-1,800°C (932-3,272°F), covering applications from moderate-temperature boilers to hot reheat and reforming furnaces. Accuracy is ±1% of reading or ±5°C (whichever is greater) for the lower range and ±1% for the higher range. The 640 × 480 pixel detector operates at up to 60 fps with Gigabit Ethernet connectivity, delivering real-time thermal data for continuous furnace optimization via ImagePro software. |
| Why use an MWIR camera instead of NIR or LWIR for furnaces? |
The 3.9 µm MWIR wavelength is critical for seeing through furnace atmospheres. Combustion processes using dirty fuels produce smoke, particulates and luminous flames that blind visible, near-IR (NIR) and long-wave IR (LWIR) cameras. The mid-wave IR band cuts through these obscurants, delivering clear thermal images operators need for safe, efficient furnace management. This wavelength advantage is why MWIR borescopes are the standard for furnace thermal imaging in demanding industrial environments. |
| Which furnaces and processes is the MWIR-b-640 best suited to? |
The MWIR-b-640 is the preferred solution for steam methane reformers, reheat furnaces, biomass and coal-fired boilers, cement kilns, waste incinerators, heat treatment and annealing furnaces, and ethylene cracking furnaces. Anywhere combustion atmospheres, dirty fuels or heavy particulates create visibility challenges, the MWIR-b-640 delivers the clear thermal images and accurate temperature data that operators need for process optimization, efficiency improvement and predictive maintenance. |
| How is the MWIR-b-640 protected from the heat, and what happens if cooling fails? |
LAND offers integrated water and air cooling options built into the borescope housing. Water cooling provides maximum thermal protection for high-temperature applications, while air cooling suits moderate environments where water supply is impractical. An auto-retraction system automatically withdraws the borescope if cooling fails, water flow drops, air pressure is lost, power is interrupted, or tip temperature exceeds safe limits—protecting your investment and ensuring continuous operation without operator intervention. |
| What software and connectivity does the MWIR-b-640 use? |
The MWIR-b-640 integrates with LAND's ImagePro advanced image processing software for control, monitoring, analysis and long-term data capture. It connects via Gigabit Ethernet/PoE (with fiber-optic option) plus Open Data Interface, Modbus TCP/IP and configurable I/O modules. The patented background reflection compensation algorithm corrects for furnace wall reflections in real-time. Long-term trending enables early detection of tube leaks, refractory degradation and temperature variations for predictive maintenance. |
