Thermography in Mechanics
Precise Inspection of Mechanical Components with Infrared Cameras
Visualize mechanical stress: Thermography detects friction, tension, and compression through temperature changes
Early fault detection: High-resolution thermal imaging reveals issues before visible damage occurs
Analyze fast-moving processes: High frame rates capture dynamic motion in real time
Engineered for tough environments: IP67-rated cameras with optional protection for extreme conditions
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 240 Hz in full frame mode of the inspection cameras out of the VarioCAM® High Definition series series or up to 105,000 Hz with the ImageIR® camera 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.
