The NIR-B-640 uses advanced near-infrared spectral filtering to provide a clear view into the furnace gases

Measuring in a range from 600 to 2000°C (1112 to 3632°F), the NIR-Borescope-640 (NIR-B-640) provides a high-resolution thermal image with real-time, continuous, high-accuracy temperature readings.

It utilises the latest wide dynamic range imaging technology, providing the highest available temperature reading accuracy over the entire wide temperature range, for accurate, continuous temperature profiling of the furnace and stock.

The NIR-B-640 uses advanced near-infrared spectral filtering to provide a clear view into the furnace gases, allowing highly accurate temperature measurement point data to be taken, stored, and trended over the lifetime of the furnace.

An advanced near infrared spectral filtering system provides a clear view through the furnace gases, allowing highly accurate temperature measurement point data to be taken, stored and trended over the lifetime of the furnace.

With specially designed image and data processing software that supports long-term data trending, the NIR-B-640 is ideal for applications in cement kiln and cyclone furnaces, reheat furnaces, continuous casting (zone 1), heat treatment and annealing furnaces.

WIDE MEASUREMENT RANGE
Utilising LAND’s latest wide dynamic range imaging technology, the NIR-B-640 can accurately measure ‘cold’ and ‘hot’ areas in one frame or image. This allows the entire process to be monitored without switching to different temperature ranges during operation.

MULTI-VIEW AREA 
The high-resolution image, combined with the wide-angle (90o) field of view, allows multiple areas in the lane to be imaged and measured simultaneously. With advanced digital communications, the image and data can be viewed in real-time in a safe area control room.

ADVANCED IMAGING SOFTWARE
The performance of the furnace can be monitored and optimised through the IMAGEPro thermal imaging software package. This easily identifies hot and cold areas and visualises uneven heating, with corrections viewed in real time.

COOLING OPTIONS
LAND borescopes are designed with a choice of cooling solutions to ensure optimal performance even in extreme temperatures. These cooling systems are built directly into the protective housing of the borescope to maintain the equipment’s integrity and prevent overheating during extended use. LAND offers two primary cooling options: air and water.

Water cooling option provides the most efficient thermal protection by circulating water through the housing, effectively managing higher temperatures and extending the lifespan of the equipment. Air cooling option is available for applications where water cooling is not possible and where the equipment is exposed to moderate heat levels, ensuring consistent airflow to regulate the internal temperature of the borescope.

This dual cooling approach ensures that the borescopes can be used in a wide range of industrial settings, from routine inspections to high-temperature processes, while maintaining accurate and reliable performance.

High Temperature Borescope

The NIR-B-640 is LAND’s thermal imaging solution for prolonging furnace lifetime, optimising production throughput, reducing energy consumption and improving stock temperature.
