Radiometric Imaging — Absolute Temperature on Every Pixel

The Workswell WIC Industrial is a robust and precise thermal imaging system designed for continuous industrial monitoring. It captures accurate radiometric data, measuring absolute temperatures across the full field of view for process optimisation, safety, and predictive maintenance. Unlike a standard thermal camera that only produces a false-colour thermal image for visual inspection, a radiometric camera measures the actual temperature at every pixel in the image — each pixel value is a calibrated temperature measurement in degrees Celsius (or Kelvin), not merely a relative intensity value. This per-pixel absolute temperature data is what enables direct integration into automated closed-loop control systems (where a temperature reading at a specific pixel location or zone triggers a process action), alarm systems (where any pixel exceeding a threshold temperature triggers an alert), and automated quality inspection stations (where a temperature distribution pattern is compared against a specification to pass or reject a product).

LWIR Spectral Range — Why 7.5–13.5 μm for Industrial Thermal Monitoring

The WIC Industrial’s spectral range of 7.5 to 13.5 µm (Long-Wave Infrared, LWIR) is the most widely used band for industrial and scientific thermal imaging. In this spectral window, essentially all solid materials and most liquids emit thermal radiation efficiently (high emissivity), and the atmosphere is largely transparent to these wavelengths, enabling accurate temperature measurement without significant atmospheric absorption errors. The LWIR band also covers the peak thermal emission wavelength of objects at temperatures from room temperature up to several hundred degrees Celsius — making it ideal for the majority of industrial process monitoring targets including electrical equipment, mechanical components, process vessels, and building infrastructure. For the very highest temperature targets (molten metals, combustion processes up to 1,500°C), the camera’s extended range accommodates these applications within the same LWIR platform.

Radiometric Precision — Absolute Temperature on Every Pixel

Captures absolute temperature values for every pixel, enabling precise process control, threshold-based alarms, and automated quality inspection. This per-pixel radiometric capability is what distinguishes the WIC Industrial from a visualisation-only thermal camera and enables direct integration into industrial automation and control systems.

Continuous 24/7 Monitoring

Designed for 24/7 operation in industrial production environments. Continuous fixed-mount monitoring detects thermal anomalies the moment they develop — not only during periodic inspection visits — enabling the earliest possible alert of developing faults, process deviations, and safety-critical temperature exceedances across unattended production shifts.

High Thermal Sensitivity — 30 mK NETD

Detects subtle temperature variations as small as 0.03°C, ensuring early fault detection. The 30 mK NETD enables the camera to identify nascent electrical faults (developing connection resistance), early-stage bearing friction, and marginal process temperature deviations well before they progress to component failure or product quality rejection.

Real-Time Radiometric Data Output

Supports live radiometric thermal imaging with Gigabit Ethernet digital connectivity for automation and control systems. Full per-pixel radiometric data is transmitted at the camera’s frame rate over a single GigE cable that also delivers PoE power, simplifying installation to a single-cable connection at the camera mount point.

Compact Design and Easy Integration

Fits seamlessly into production lines, laboratories, or automated inspection setups. Compact form factor facilitates mounting at tight integration points, and Windows and Linux SDK support enables custom software integration with SCADA systems, PLC-based alarm systems, and machine vision platforms.

Durable Industrial Build — IP66/IP67, −50°C to +200°C

Rugged IP66/IP67 enclosure and −50°C to +200°C operating temperature range ensure reliable operation in outdoor environments, high-temperature process areas, cold storage facilities, and dusty industrial production environments without additional camera housing or protection measures.

Predictive Maintenance and Process Control Integration

Enables predictive maintenance by detecting thermal anomalies early, enhances product quality through precise temperature control, and reduces downtime by identifying overheating or failures in real time. Continuous radiometric data logging enables trend analysis that distinguishes gradual thermal degradation from sudden faults, supporting condition-based maintenance planning.

Industry 4.0 and Automation System Ready

Easy integration with automation and Industry 4.0 systems through GigE Ethernet connectivity and SDK support. Continuous monitoring ensures compliance with safety standards requiring documented temperature monitoring records for regulated processes.
