SKF TMTI 2 Advanced Handheld Thermal Imaging Camera

Overview

The SKF TMTI 2 is a professional-grade, handheld thermal imaging camera engineered for predictive maintenance, condition monitoring, and non-contact temperature diagnostics in industrial, electrical, and mechanical environments. Based on uncooled microbolometer detector technology operating in the long-wave infrared (LWIR) spectral band (8–14 µm), the TMTI 2 captures spatial thermal distributions across surfaces without physical contact. Its 160 × 120 pixel focal plane array delivers sufficient resolution for identifying localized anomalies—such as overloaded connections, bearing friction hotspots, insulation defects, or steam trap failures—while maintaining portability and operational simplicity. Designed for field technicians and reliability engineers, the instrument integrates real-time thermal visualization with quantitative spot measurement capabilities, enabling rapid assessment of thermal gradients, comparative analysis between components, and documentation of thermal behavior over time.

Key Features

• Uncooled 160 × 120 microbolometer detector ensures stable performance without cryogenic cooling, reducing power consumption and mechanical complexity.
• Manual focus system with 30 cm minimum working distance supports precise targeting on small or distant components.
• Integrated Class II laser pointer provides visual alignment reference for accurate spatial correlation between thermal image and physical location.
• Dual movable crosshairs enable simultaneous measurement of two user-defined points, supporting differential temperature (ΔT) calculations critical for evaluating thermal resistance or heat transfer efficiency.
• Emissivity compensation from 0.20 to 1.00 in 0.01 increments allows calibration for diverse surface materials—including oxidized steel, painted enclosures, copper busbars, and composite insulation—improving measurement fidelity.
• Four selectable color palettes (Iron Red, Rainbow, Grayscale, High-Contrast) optimize visual interpretation under varying ambient lighting and target contrast conditions.
• Ruggedized engineering plastic housing meets industrial drop-test requirements and provides protection against incidental impact during plant floor use.
• USB Type-B interface enables direct image transfer and firmware updates; bundled PC software supports report generation compliant with ISO 18436-1 and ISO 13374-1 frameworks for machinery condition monitoring.

Sample Compatibility & Compliance

The TMTI 2 is optimized for non-destructive, surface-based thermal evaluation of stationary and rotating equipment—including motors, transformers, switchgear, HVAC ducts, refractory linings, and process piping. It does not require sample preparation or emissivity masking and functions effectively on electrically live systems when used within safe working distances per NFPA 70E and IEEE 1584 guidelines. While not certified for intrinsically safe (ATEX/IECEx) environments, its design aligns with general-purpose industrial safety expectations. Data acquisition and storage comply with basic traceability principles required under ISO 55000 asset management standards. The device supports documentation workflows compatible with CMMS integration via exported JPEG and CSV formats.

Software & Data Management

The included PC software suite facilitates post-capture analysis, annotation, and standardized reporting. Users can overlay measurement markers, apply region-of-interest (ROI) statistics (min/max/mean/standard deviation), generate annotated thermal snapshots, and export PDF or Excel reports. Image metadata—including date/time stamp, emissivity setting, ambient temperature input, and lens configuration—is embedded in each saved file. The software supports batch processing of multiple thermal images and maintains audit-ready logs of user actions, satisfying foundational GLP-aligned documentation practices. No proprietary cloud platform is required; all data remains locally controlled and exportable without vendor lock-in.

Applications

• Electrical systems: Detection of loose terminations, phase imbalance, failing breakers, and capacitor bank degradation.
• Mechanical assets: Identification of misalignment, inadequate lubrication, belt slippage, and bearing fatigue signatures.
• Building diagnostics: Locating thermal bridging, moisture infiltration, and HVAC duct leakage.
• Process industries: Monitoring refractory integrity in kilns/furnaces, verifying steam trap functionality, and assessing heat exchanger fouling.
• Preventive maintenance programs: Establishing baseline thermal profiles and trending deviations over scheduled inspection intervals.

FAQ

What is the spectral response range of the TMTI 2?

The detector operates in the long-wave infrared (LWIR) band from 8 to 14 µm, optimized for ambient-temperature object emission and atmospheric transmission characteristics.
Does the TMTI 2 support radiometric video recording?

No—the TMTI 2 captures still thermal images only. Radiometric video capability is not implemented in this model.
Can the emissivity setting be locked during field inspections?

Yes—emissivity values are retained across power cycles and can be preset for common materials to streamline repetitive measurements.
Is the USB interface compatible with modern Windows and macOS versions?

The bundled software is validated for Windows 10/11 (64-bit); macOS compatibility requires third-party image viewers capable of interpreting standard JPEG metadata tags.
How is calibration maintained over time?

The TMTI 2 employs factory-calibrated non-uniformity correction (NUC) algorithms. Periodic internal shutter-based recalibration is performed automatically on startup and may be manually triggered via menu command to ensure thermal stability.
