Thermal Imaging Thru-Wall System for High-Temperature Furnaces

Real-Time, Accurate, Near-Infrared (NIR) Temperature Measurement

Lenox Furnace Camera HD NIR-Thermal Imaging Systems provide real-time, accurate, non-contact
temperature measurement and monitoring from 324,064 individual temperature points via a high speed digital connection. Designed to be installed through a small, 3-1/2 inch (89mm) opening in the wall of a furnace or combustion chamber, the high resolution, infrared camera employs a stainless steel housing with a steel triple wall laminar flow for efficient water-cooling of the camera and integrated low consumption air-purging that keeps the lens clear of particulate, enabling operation in hostile environments up to 4250ºF (2245ºC). The Lenox near-infrared (NIR) camera’s specially selected short wavelength minimizes temperature measurement errors due to variations in target surface emissivity. An Automatic Retract System is available that pulls the thermal imaging camera back should a loss of water-cooling or air occur, preventing possible over-temperature damage.

Lenox Image Processing Software allows high resolution images and data to be viewed, manipulated,
recorded and archived and to remotely control the camera. Advanced image processing and digital
communications include features and benefits like:

  • Accurate and real time temperature measurement, recording and analysis
  • Analytical and process control functions e.g. multiple point or user-defined areas of interest temperature measurement, multiple temperature line profiles, isotherms, histograms, trending, emissivity adjustment, delta temperature measurement, background correction and choice of color pallets
  • Automatic storage of images and video on triggered measurement or high/low alarm conditions
  • Optional RS485 Input/Output (I/O) modules for software integration to a PLC or DCS
  • Analyze stored data offline
  • Information exchange via TCP/IP protocol

Lenox NIR-Thermal Imaging Camera System applications include steel annealing and reheat furnaces, glass furnaces, cement kilns, black liquor boilers, power utility boilers (superheater inspection - slag buildup), and other high temperature furnace, kiln, and oven environments.
