SUMMARY

'Drift' in strain gauges refers to the tendency of the gauge to deviate from actual readings due to temperature variations. This phenomenon is critical when selecting strain gauges for testing, as it is essential to choose gauges that closely match the parent material to minimize drift. Understanding this concept is vital for accurate measurements in engineering applications.

PREREQUISITES
  • Understanding of strain gauge technology
  • Knowledge of temperature effects on materials
  • Familiarity with material selection for engineering applications
  • Basic principles of measurement accuracy
NEXT STEPS
  • Research temperature compensation techniques for strain gauges
  • Explore material properties and their impact on strain gauge performance
  • Learn about the calibration processes for strain gauges
  • Investigate the effects of environmental conditions on measurement accuracy
USEFUL FOR

Engineers, researchers, and technicians involved in material testing, structural analysis, and precision measurement who need to understand the implications of drift in strain gauges.

when talking about strain gauges, what does 'drift' refer to exactly?
 
Engineering news on Phys.org
Drift refers to a strain gauge's tendency to deviate from the actual reading due to variations in temperature. It is the main reason when selecting gauges for testing that they be as close to the parent material as possible.
 
thanks!
 
Lost in PF

Not sure if this is correct form but I have a question. I am building,(in the process of planning to build) a hovercraft. But not just a hovercraft, which is itself exciting enough, but one that uses very little horsepower to operate. I feel that I need a least a basic knowledge of wing shapes or contours, not sure the correct label, in order to design my device properly. This knowledge should link together Reynold's number with these shapes. Who can help me with this idea?
 
Normouse, you seem to have an off-centre idea of what a hovercraft is. If you're talking about wings, you probably have a WIGE (Wing In Ground Effect) vehicle in mind. That is a totally different animal.
By the bye, this should be a separate thread, since it has nothing to do with the original post.
 
New type of hovercraft

Maybe this is the wrong thread but I know exactly what a hovercraft is. How do I get on the correct thread?

You simply start a new thread under the appropriate sub-forum. If unsure, PM a mentor.
