Dual-Spectrum Thermal-Visible Inspection System with 160×120 IR Microbolometer and 2.0 MP Visible Camera

Product Overview

The Sugia OmniScope S3 is a dual-spectrum inspection system that combines an uncooled vanadium oxide (VOx) microbolometer focal-plane array with a separate 2.0-megapixel visible-light CMOS camera in a single 8.5 mm diameter probe head. Unlike general-purpose videoscopes with a “thermal accessory,” the S3 treats the two spectral channels as co-equal data sources with a dedicated fusion engine that overlays thermal data onto visible-light imagery for instantaneous hotspot localization.

The thermal channel uses a 160 × 120 pixel sensor with 12-micron detector pitch, operating in the 8–14 µm long-wave infrared (LWIR) band. This is not a megapixel-resolution camera: it is a radiometric temperature-measurement instrument that reports temperature values for every pixel in the array with ±2 °C or ±2% accuracy (whichever is greater) across a -20 °C to +400 °C measurement range. The thermal field of view is 57° × 44°, matched approximately to the 80° diagonal visible channel FOV for effective image fusion.

The S3’s MSX (Multi-Spectral Dynamic Imaging) fusion engine extracts edge-detail information from the visible-light image and superimposes it on the thermal image, creating a composite that provides both radiometric temperature data and visible-context spatial reference. This is particularly valuable in electrical inspection, where a thermal hotspot on a busbar connection can be simultaneously localized to a specific bolt or clamp in the visible reference image.

Key Engineering Features

• Uncooled VOx Microbolometer: 160 × 120 pixel array, 12-micron pitch, 8–14 µm spectral response; radiometric temperature measurement at every pixel; ±2 °C or ±2% accuracy.
• 2.0 MP Visible-Light Channel: Separate 1/3-inch CMOS sensor with 1920 × 1080 resolution; independent LED illumination ring; captures visual-reference images simultaneously with thermal data for location context.
• MSX Image Fusion Engine: Real-time edge extraction from the visible channel overlaid on the thermal image; user-adjustable fusion blend ratio (0–100% visible contribution) via console touchscreen slider.
• Radiometric Spot and Area Measurement: User-positioned spot meter, rectangular area box (min/max/average temperature), and automatic hot/cold-spot tracking. Isotherm threshold alert with audible alarm when user-defined temperature limits are exceeded.
• CAT IV 600V Safety Rating: Probe and handpiece are certified to IEC 61010-2-030 CAT IV 600V for direct contact with energized electrical conductors in utility switchgear and distribution panels.

Target Applications

• Electrical Distribution: MV/LV switchgear busbar connection thermography during energized condition; circuit-breaker terminal overheating detection; transformer bushing connection temperature surveys; panelboard branch-circuit load-imbalance thermal identification.
• Refractory & Insulation: As an NDT pipeline inspection tool, the S3 detects furnace refractory hot-spots indicating lining thinning or failure; surveys steam-pipe insulation-jacket thermal energy loss; maps kiln shell temperature for refractory-wear trending.
• Building Envelope: Cavity-wall insulation void thermal detection, HVAC duct leakage thermal identification from internal duct surveys, underfloor heating pipe continuity verification.
• Process Equipment: As a heavy machinery diagnostic videoscope, the S3 maps heat-exchanger tube-bundle temperature distributions for flow-maldistribution diagnosis; assesses steam-trap thermal performance; monitors rotating equipment bearing-housing temperatures through guard apertures.
