NIR-b data sheet - .PDF file.

The NIR-b thermal imager from Land Instruments eliminates the drawbacks of traditional methods of monitoring furnaces.

According to the company, operators of refractory-lined furnaces and kilns typically cut large openings in the refractory wall to view critical areas. This can result in significant heat loss as well as difficulty in keeping the opening free from debris. Traditional methods for monitoring furnaces include: visual inspection, which can take hours to complete and is not continuous; visual camera, which does not provide temperature readings; and thermocouples, which are subject to regular failure or loss of connection.

The NIR-b is installed into the furnace through only a small opening in the outer refractory wall to give a precise, continuous internal temperature profile.

Key features and benefits 

  • 24/7 monitoring that guarantees accurate, reliable and continuous data with no blind time
  • Viewing angle of 44º and 90º inside the vessel that maximises temperature coverage across 324,000 data points 
  • Dedicated software that provides key measurement data, including data points, areas of interest, automated alarms and long-term data trending
  • High-performance water-cooling system with low-water flow requirements for even the highest-temperature furnaces
  • Integrated air purge that keeps the optical system clear of debris while consuming minimal instrument air
  • Short wavelength sensor with low sensitivity to emissivity changes that can be used through glass or quartz view ports
  • Wide range of mounting options, including the most commonly available options to ensure easy installation and ease of use and probe lengths for the best available fit for every installation
  • Thermocouple at NIR-b tip that alarms for removing the instrument to prevent damage if maximum temperatures are exceeded
