Hi,
I'm currently working on a test bench which incorporates a small spring that needs to be evaluated. The test bench counts a certain component movement until the spring fails.
The spring looks like a rounded capital A with long parallel side (below the cross bar if you like) the diameter if the springs wire is approx 0.25 - 0.5 mm. the distance between the ends of the legs is approximately 5mm
Now, I originally intended for both protruding legs to activate 2 small micro switches but the additional load has influenced the data. The physical dimensions prohibit the use of an opto slot type sensor (even SMD)
The only thing I can think of is a strain gauge on double sided sticky foam pads so that the spring would touch it (and deform it) at the end of movement - would this work and could I use one sensor for both legs (legs slghtly bends sensor in 2 places.
Hope this makes sense
Thanks
Doc
