testo 477: Fast Measurements on Fans, Impellers, and Lathes
The testo 477 instrument allows for fast measurements on objects and areas of very small size, direct access to which is impossible without interrupting the production process. Such measurements are possible due to the lack of necessity for reflective markers. The powerful LED stroboscope testo 477 allows for the creation of a visual effect of slow motion for fast-moving objects and can determine the rotational speed up to 300,000 RPM.Maintenance and Quality Control in Production Environments
The testo 477 instrument allows for drawing conclusions about the nature of rotation and vibration of objects. “Analysis using flashing light” helps to identify:- Irregularities in mechanical equipment systems and components (e.g., “vibration hotspots”).
- Problems in the operation of packaging equipment and vibratory conveyors.
- Oscillation amplitudes.
- In the textile industry: control of thread guides on knitting machines.
- In printing: control of the uniformity of printed image quality on printing presses.
