Automotive How Can You Measure Wood Plate Thickness from One Side?

AI Thread Summary
Measuring wood plate thickness from one side can be achieved using acoustic methods or analog proximity sensors. Acoustic techniques depend on the wood type and cut orientation, while analog sensors can measure thickness with an accuracy of one part in 4000. A specific application involving an inductive sensor is referenced in US Patent 6,793,865. The presence of nails or fasteners may affect measurement accuracy, and the material characteristics on the opposite side are crucial for detection. Understanding the required accuracy and the conditions on the other side of the plate is essential for effective measurement.

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..."

:confused:
 
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?
 
Thread 'What type of toilet do I have?'
I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
