Border Security & Surveillance

Sensors Unlimited's calibrated short wave infrared (SWIR) thermography solutions, using InGaAs cameras, offer advanced, continuous monitoring for high-temperature industrial furnaces. These furnaces are critical in industries such as petrochemical processing and pulp and paper manufacturing, where precise thermal control is essential for safety, efficiency, and operational longevity.

Operating in the 900–1700 nm wavelength range, InGaAs cameras are capable of detecting black body radiation corresponding to temperatures above 200°C. This makes them well-suited for observing the internal conditions of active furnaces. When paired with appropriate industrial enclosures, these cameras withstand harsh environments while delivering reliable performance.

A key application of this technology is the detection of slag buildup inside the furnace—a common issue that, if left unaddressed, can reduce efficiency or cause serious damage. SWIR cameras provide clear, high-resolution imaging of furnace interiors, allowing operators to identify problem areas and take corrective action before costly disruptions occur.

In addition to slag detection, these systems help monitor overall furnace temperature distribution and structural integrity. Real-time thermographic feedback supports predictive maintenance, reduces unplanned downtime, and improves safety for operators and equipment alike.

Calibrated SWIR thermography not only enhances visualization but also provides quantifiable thermal data, allowing operators to maintain optimal operating conditions. As a result, Sensors Unlimited’s InGaAs camera systems play a vital role in industrial process control, offering a robust and intelligent solution for furnace monitoring in demanding industrial applications.
