NIR-Borescope-640-EX

The NIR-Borescope-640-EX is a short wavelength radiometric infrared borescope imaging camera for steam reformer and cracker tube continuous temperature measurement and furnace optimisation and monitoring. 

ATEX and IECEx approved to Ex nA IIC T4 Gc for use in Zone 2 gas atmospheres, and CSA Certified for US and Canada to Class I, Division 2, Groups A, B, C, D T4,  the NIR-B-640-EX provides a high resolution thermal image with real time continuous high accuracy temperature measurements of both the tube wall and refractory wall surface.  The camera measures temperatures in the single range 600 to 1800 °C (1112 to 3272 °F) and utilises the latest wide dynamic range imaging technology. This is ideal for applications with a high differential temperature in the field of view such as tube and furnace walls.

With the NIR-B-640-EX it is possible to use the proven technology of the NIR thermal imager to accurately and continuously profile the temperature of the reformer, improving data accuracy through automation and at the same time reducing the risk to personnel by removing the need for an operator to be in the hazardous area on a regular basis.  The NIR-B-640-EX uses the shortest wavelength to minimise errors associated with varying emissivity, allowing highly accurate temperature measurement point data to be taken, stored and trended over the lifetime of the reformer or cracker. The image and data processing software supports long term data trending, allowing process optimisation to be achieved, combined with potentially avoiding catastrophic failure.

The high resolution image combined with the wide angle field of view (90° x 67.5°, 44° x 33°) allows multiple reformer or cracker tubes in the lane to be imaged and measured simultaneously.  With advanced digital communications the image and data can be viewed real-time in the control room in the safe area.  The image also allows the user to monitor and optimise the performance of the furnace; easily identifying hot and cold areas and any uneven heating and gas mix can be visualised with corrections viewed in real-time.  During start-up phases any burners that are not operating correctly can be clearly identified and the effect of any impinging flames can be seen.

Enables optimum process control through enhanced thermal imaging.
REAL-TIME THERMAL DATA - COMBINED WITH HIGH RESOLUTION VISUAL IMAGE
allows true real-time furnace optimisation and the opportunity to improve energy efficiency without degrading reformer lifetime.

HAZARDOUS AREA COMPLIANT 
The NIR-B-640-EX is ATEX and IECEx approved to Ex nA IIC T4 Gc for use in Zone 2 gas atmospheres, and CSA Certified for US and Canada to Class I, Division 2, Groups A, B, C, D T4. A three-year warranty guarantees reliability. 

The NIR-B-640-EX is an invaluable tool in prolonging reformer tube life time, optimising production throughput and reducing energy consumption. 

Borescope Increases Know-How by Continuously Measuring Temperature of Tube Walls for Air Liquide
Air Liquide, the world leader in gases, technologies and services for industry and health, has implemented AMETEK Land’s Near Infrared Borescope (NIR-B) 3XR, an enhanced thermal imager, and now is gaining in know-how by continuously measuring temperature of tube walls within its steam methane reformers (SMR).
