How Can You Measure Wood Plate Thickness from One Side?

Click For Summary
SUMMARY

The discussion focuses on measuring wood plate thickness from one side using acoustic methods and analog proximity sensors. Acoustic methods depend on the wood type and cut orientation, while analog proximity sensors, such as those discussed in US Patent 6,793,865, can measure thickness with an accuracy of one part in 4000. The recommended sensing range for these sensors is between 0.040" and 1". The conversation emphasizes the importance of material characteristics and boundary detection for accurate measurements.

PREREQUISITES
  • Understanding of acoustic measurement techniques
  • Familiarity with analog proximity sensors
  • Knowledge of wood types and their properties
  • Basic principles of boundary detection in materials
NEXT STEPS
  • Research acoustic measurement techniques for wood thickness
  • Explore the specifications and applications of analog proximity sensors
  • Study US Patent 6,793,865 for detailed sensor applications
  • Investigate boundary detection methods in material science
USEFUL FOR

Woodworkers, engineers, and anyone involved in material measurement and testing will benefit from this discussion, particularly those seeking innovative solutions for measuring wood thickness without access to both sides of the material.

I have access to only one side of the plate, i.e. cannot clamp both sides of the plate to measure.
Is there any way, perhaps acoustic methods, to measure a plate thickness from only one side?

Drill a hole, then put a plug or screw in the hole if a hole is a problem.
Acoustic methods will depend on the type of wood and the orientation of the cut.

"...an inductive sensor positioned on one side of the material to be measured and a metallic object placed on the opposite side..."

No confusion at all. @DaveC426913 simply did a better job of reading the OP than I did. :oops:

What is a “plate”?
Does it include nails or other fasteners?

To be detected, there must be a boundary where the material characteristics change.

What is on the other side of the wooden plate?
How accurately do you need to know the thickness?
