I think the difficulty with this is that the measuring device would have to be taped down to the surface of the gelatin containing the tube. Sorry I should have said that above with the constraints of the project. It seems the proximity sensor would have to have some standoff distance to...
Thanks for the ideas,
Unfortunately we can't have anything penetrate the tube. So the reason why I was thinking a strain gauge was that 1) I need something that is cheap to make for one time use and toss it in the garbage due to contamination. I could use a Doppler device on a miniature scale...
Thanks for the follow up:
Lets say the baseline pressure in the tube is 70mmHg and that has zero displacement of the near and far wall of the tube. By near I mean the wall of the tube closest to our gauge and the far wall is the side opposite that. When pressure in the tube increased to let's...
Thanks for getting back to me.
The gelatin is not transparent. So you can't optically see the pulsation too easily. Also I think a camera would be too big anyway. Whatever gauge is used to measure the stretch would essentially have to be able to be embedded in a 1inch x 0.5inch piece of tape...
Hey guys/gals so here is my problem, I am trying to be able to passively measure the mechanical vertical deflection of fluid passing through an elastic tube approx 1cm in diameter with 0.5mm thick wall that is embedded into the surface of a gelatin mold. Pressure of the flow through the tube...
