Inspections of Mechanical Components

Mechanics = movement = heat
Thermal imaging makes it visible

  • Thermography can indicate mechanical stress caused by pressure, draft and friction
  • Inspections from safe distance possible
  • Fast infrared camera systems can resolve movements and indicate faults precisely in time

Acquisition of Temperature Changes Caused by Draft, Pressure or Friction During Operation

Mechanical components get loaded by pressure, draft or friction during operations. Those load types will all result in an increased temperature. Like this the running of a spindle will result in friction even though being well lubricated. If the spindle is not well positioned the friction will even increase. Infrared camera systems provide a fast overview of the status of the operation long before indications can be seen without such a device.

Thermography Allows Inspections from a Safe Distance

The non-contacting nature of the thermographic measurements is a big advantage. Maintenance personnel can inspect rotating or other fast moving machine parts from outside a dangerous zone. Inspections are additionally eased up as a visualisation of the inspected area is provided.

Thereby, in case of emergency, first actions can be taken even before any profound analysis of the data has been carried out. Preset temperature thresholds for alarming and other personalized settings also help to get maintenance teams productive in very short time.

Fast Movements Can Be Resolved by Infrared Camera Systems with High Frame Rates

Many mechanical movements run at high speeds. Infrared camera systems should be able to resolve such movements to selectively detect faults. Frame rates of up to 60 Hz in full frame mode of the inspection cameras out of the VarioCAM® High Definition series provide with exactly this advantage. Combined with sequence analysis tools of the thermographic software IRBIS® 3 smallest faults can be found right in the moment of emergence and subsequently those faults can be eliminated.

  • Live: Thermography Solutions for Power Electronics – Precise, Non-contact and High-speed

    Power electronics is a key enabler for the future renewable energy based grid and plays an important role for improving the efficiency of power devices. E-mobility, industrial pumps and transportation systems benefit from the latest technologies of this research direction. They ask for faster active components, high power densities of miniaturized systems as well as absolute reliability.

    Further information about MicroScan

    MicroScan – Quadrupling the Number of Pixels

    Displaying measurement objects with extremely low noise and fine resolution – this is what MicroScan is for. Using this function, the native pixel number of the detector can be quadrupled. This results in thermograms of better image quality with geometric resolutions of more than 5.2 Megapixels. Each pixel in the image represents a true temperature reading, not an interpolated pixel.

    Motor Focus for ImageIR® Full Lenses – More Comfort

    All interchangeable standard lens systems of the ImageIR® series can be combined with a motor focus unit, which is controlled by the camera operating software. It enables precise, remote and fast focusing. In addition, an autofocus function is available which operates reliably even with low image contrasts.

    Further information about permanent autofocus

    Permanent Autofocus

    Constantly changing object scenes require manual or automatic refocusing. The integrated permanent autofocus function makes this task easier. In the case of a change of scene, the camera automatically applies the optimum focus setting quickly and precisely. The completely innovative, very powerful autofocus system is laser-based and works extremely reliably. Even under unfavourable environmental conditions, such as poor lighting conditions, darkness or low thermal contrasts on the measuring object, this function provides exactly focused thermal images.

    High-quality Light Metal Housing

    The very robust light metal housing is available with the protection degree IP67 and protects the camera against mechanical and thermal stress. In conjunction with protection degree preserving LEMO® connectors, it is excellently suited for use in harsh industrial environments. For applications under extreme environmental conditions, suitable protective housings are also available, e.g. made from stainless steel, which can optionally be equipped with a cooling and heating system.

  • InfraTec thermography - Geometrical Resolution

    Geometrical Resolution – Efficient Analysis of Complex Assemblies

    InfraTec's infrared cameras with cooled and uncooled detectors have native resolutions up to (1,920 × 1,536) IR pixels. Spatially high-resolution thermograms ensure that components and assemblies are imaged down to the smallest detail and thus defects can be reliably detected and precisely localised.
