Land, a leader in industrial infrared temperature measurement, is introducing thermal imaging systems to overcome remote measurement challenges in liquid aluminium.

Its advanced radiometric infrared borescope MWIR-b-640 thermal imager with spectral filtering uses a mid-range wavelength of 3.9 μm to achieve a clear, continuous view through heavy smoke and hot furnace atmospheres, overcoming the difficulties caused by reflections from the hotter walls, fumes and particulates, dross build-up and surface materials which impact the measured signal.

With a wide-angle field of view, the camera allows multiple areas to be imaged and measured simultaneously, enabling high-resolution furnace measurement image data to be taken, stored, and trended over the lifetime of the furnace.

The continuous temperature allows aluminium operators to closely control the process, plan tapping and pouring operations, and ensure minimal energy consumption.

The MWIR-b-640 is supported by the advanced ImagePro thermal imaging and data processing software, providing operators with a clear view of critical areas within the furnace with over 300,000 image pixels.
